Depending on what you name your save file, the name inputted will act as a seed that determines the position of the twinkling white stars in the night sky, while the blue stars and larger red planet remain in the same position. Since there is a character limit of 8 characters for a name, the number of possible variations is estimated to be somewhere under 5.3 billion, the key word being "under" as this cosmetic feature does not utilize all 127 characters available, so the actual number is bound to be lower.

In an article for the September 2000 issue of Nintendo Power, Jason Leung, the writer for the game's English-language script, claimed that the South Clock Town Business Scrub's allusion to his work keeping him away from his wife is a nod to the tribulations that the developers at Nintendo of Japan were going through while working on the game.

In the game's files are unused graphics that say "Game Over" and "Continue Playing?" In the final game, losing all of the player's hearts will warp said player back to the beginning area, and Spoiler:letting the moon fall will result in a lengthy cut scene followed by the famous words, "You've met a terrible fate, haven't you?" accompanied by the Happy Mask Saleman's chuckle.

In the game's files is unused text regarding the player's stolen Hero Shield. It's suggested that the shield would've been stolen, resulting in the player going to the Curiosity Shop to get it back.

"You bought back the Hero's Shield
that was stolen from you.

In the future, watch out for
swooping birds on your travels."

In the game's files are two unused texts regarding the Hylian Loach. This may suggest that said fish would've been found in both a bottle and without one.

The first text states:
"It's a Hylian Loach in a bottle!
An illusory fish that
few have caught...

And it came in a bottle!
What a find!"

Another one states:

"You got the Hylian Loach!
An illusory fish that
few have caught..."

There's unused text regarding getting a seahorse in a bottle. In the final game, the player must have an empty bottle to get a seahorse.

"You traded for the Seahorse.
And it came in a bottle!
You should hurry and return it
to its home at Pinnacle Rock."

Inside the moon, there is a bird that flies around the tree on the plain. This bird was originally in the beta version of Ocarina of Time, but went unused and was repurposed for Majora's Mask.

Eiji Aonuma has stated that Anju and Kafei's characters were inspired by the 1998 North Korean Taepodong missile crisis. During the game, Spoiler:Link must help Kafei retrieve a wedding mask so that he can marry Anju mere minutes before the moon is set to annihilate Clock Town.

In the North American commercial, a woman can be heard saying "Though I walk through the valley of death, I shall fear no evil."

This is a paraphrasing of the first half of the Bible verse Psalms 23:4, "Yes, though I walk through the valley of the shadow of death, I will fear no evil: for you are with me; your rod and your staff they comfort me."

An unused fishing mini game can be found in the game's data. It would have been similar to that of the fishing in Ocarina of Time. Fish and the owner of the fishing mini game can be spawned into the game by modifying the data, but using the fishing rod will frequently cause the game to crash.

Zelda was originally going to use a flute to teach Link the song of time, but the instrument was swapped for an ocarina.

One possible reference in the game occurs during the final boss fight against Majora's Incarnation; he sometimes hums what sounds like the melody to the Death Mountain Dungeon from the very first Legend of Zelda

After Kafei gives Link the Pendant of Memories, he asks Link to keep it "a secret to everybody", a reference to the popular quote from The Legend of Zelda.

During early trailers of the game Zora link, Deku Link and Goron Link had their instrument icons instead of the ocarina. It's unknown why this feature went unused in the original game but it was later reused in the 3DS remake.

After playing the Song of Soaring, the map that displays locations Link can travel to comes up. The locations of the Southern Swamp and Windfall are displayed incorrectly. The Southern Swamp is shown to be east of Woodfall, but the player must travel east from the Southern Swamp in order to go to the Old Hags Potion Shop, Deku Palace and Woodfall.
This was corrected in the 3DS remake.

Two screenshots found on the game's Japanese website show Link confronting Skull Kid on top of the Clock Tower during the day. This is impossible in the final game without the use of a glitch or cheat device.

Originally, the in-game three-day system was going to be a week, but Eiji Aonuma, the game's director, thought that player's would be annoyed having to go through an entire week again and it would be hard to remember what happens each day.

During the final boss, there are flower symbols on the floor. The player can actually use these as Deku launch pads if they equip the Deku Mask.

On the morning of the 1st day, when the player finds Kafei going to the post box, using a bomb or the Blast Mask next to him will cause him to flash red as if taking damage.

On the back of Anju's grandmother's wheelchair, there's a picture of a tiger. This is a possible reference to the pet tiger owned by Granny in The Legend of Zelda: Ocarina of Time in Kakariko village, who is also Anju's grandmother's Hyrule counterpart.

There are 3 unused masks that can be found within the game's data that were likely supposed to have been worn by the Skull Kid. They're strange masks that look like Link, each rotated differently to be used in different scenarios.

The postman in Majora's Mask, who wants to flee, but can't find time for it in his schedule, shows quite the similarity to some couriers from a short story written by Franz Kafka. They want to kill themselves, but refrain from doing so due to their "oath of service".

In the Ancient Castle of Ikana, if the players goes to the south-east part of the courtyard there will be a pillar. If the player manages to get on top of it, they will find a paper airplane. The airplane cannot be picked up and has no significance whatsoever.

On the file select screen, if the player pushes start, holds up, pushes A and then pushes B twice, an alternate opening demo will play.

If the player stands in the little garden outside of the Astral Observatory in Termina Field when the Clock Tower opens on the third day, a different cutscene will play that shows the tower opening as if looking towards Clock Town from the Observatory.

Each piece of music in the Zora Hall is taken from a previous game in the series. This includes the main hall being the Zora's Domain's music from Ocarina of Time, Tijo playing part of the cave theme from A Link to the Past, Japas playing part of the dungeon theme from The Legend of Zelda, and Evan playing the Game Over song from the same game.

If the player talks to Keaton while wearing the Keaton Mask, he'll ask a series of questions. A sound is made signaling whether the answer selected is correct or incorrect. Picking the correct answer will trigger the "pause" sound from the game Excitebike on the NES.

During an early Beta version of Majora's Mask, the Fairy Ocarina was available and usable.

Through use of Gameshark or Action Replay cheats, it is possible to get "Saria's Song", as well as the "Sun's Song" from Ocarina of Time. The "Sun's Song" has no difference from Ocarina of Time, and fast-forwards time to the next day. "Saria's Song", however, doesn't do anything.

A clear impression of Skull Kid can be seen in the grass when looking towards the south entrance of Clock Town from the Astral Observatory telescope.

"Farewell to Gibdos" has a similar melody to that of the Merry-Go-Round located at Big Boo's Haunt in Super Mario 64.

In the magic hag's potion shop, Kotake is standing on a box of lemons in order to reach over the counter.

Majora's Mask was planned for release on the iQue Player, a Chinese version of the N64, and there are several screen captures from the game on the back of the iQue packaging. It's theorized that the game's dark undertones and imagery were deemed too violent to pass Chinese censorship laws, so the release was cancelled.

Though not explicitly stated in the game, the instruction booklet mentions Termina as a kind of parallel world of Hyrule.

All 4 main dungeon items pertain to the Bow. Woodfall Temple features the bow itself, while the Snowhead Temple has Fire Arrows, the Great Bay Temple has Ice Arrows, and the Stone Tower Temple has Light Arrows.

Aside from owl saves, the American release of Majora's Mask had a number of other changes made to it, both aesthetically and to its game-play, such as making dungeons easier, or simply moving objects around.

The impermanent flow of time in the first three-day cycle as Deku Link is 1.66 times faster than normal, meaning it takes only 27 seconds for each game hour to pass rather than the standard 45 seconds for every three-day cycle after it. It is in this stage of the game where NPCs and most enemies are not rendered outside of Clock Town's boundaries.

The aliens that attack Romani Ranch during the first night are based on the Flatwoods Monster, a monster that was very popular in the 1950s and 60s.

The Song of Healing has the same first six notes as Saria's song but played backwards with a different rhythm.

According to the gossip stone in Romani Ranch in the Cucco Shack, the All-Night Mask was used as a torture device.

"A torture device of insomnia called the All-Night Mask seems to be available at the Curiosity Shop..."

When the thief Sakon tries to steal the bomb bag from the Old Lady from the Bomb Shop, if Link hits the Bomb bag with an arrow, the hookshot, or another bomb, the bag will explode, killing Sakon.

At the end of the game, Skull Kid asks Link to be his friend and says, "You have the same smell as the fairy kid who taught me that song in the woods." This hints at the Skull Kid being the same one that Link sold the Skull mask to and taught Saria's song in Ocarina of Time.

The arch at the entrance to Romani Ranch is actually the same arch at the entrance to Kakariko Village from Ocarina of Time. Even the text on the sign is re-used, effectively saying "Welcome to Kakariko Village" in both games. This is more noticable in the Japanese version, which features the text in Japanese instead of the localized version's Hylian text. The Hylian text still translates to "Welcome to Kakariko Village", though.

If Link is wearing the Captain's Hat during the fight with Igos du Ikana, a cutscene will take place where he will mistake Link for Captain Keeta, a military general for the Ikana. He then realizes that Link is too tiny to be Keeta and then resumes attacking Link.

If the player equips the Bremen Mask and plays the marching melody during the Ikana Warriors mini boss battle, they will march with Link. It's quite handy to leave them open for an attack. However, it won't work with the following mini boss, Igos du Ikana, as he'll just attack Link regularly.

During development, Majora's Mask went by the name Zelda Gaiden. It was being developed for the failed Nintendo 64 Disk Drive add-on, and was to take full advantage of the hardware. The player originally had seven days to complete the game rather than three and it used the Disk Drive's internal clock to play out in real time.

In a prerelease trailer for Majora's Mask, there seems to be an unused mask that looks like Adult Link for Ocarina of Time. This mask was rumored to be a transforming mask which would turn Link into Adult Link, allowing him to use certain items. The mask was removed before the final version and young Link is capable of using all of the items directly.

If Link is wearing the Garo's Mask, the Gibdo Mask, or the Captain's Hat in the presence of Redeads, they will start dancing.

In the Astral Observatory, there is a picture of a dolphin hidden under a small pot. It's thought to be a reference to Dolphin, the Gamecube's code name at the time.

The development for Majora's Mask started out of a lack of enthusiasm to work on the unreleased expansion for Ocarina of Time for the Nintendo 64 Disc Drive, dubbed "Ura Zelda". Eiji Aonuma protested the expansion, so Shigeru Miyamoto challenged him to make a sequel for the game within 1 year, in exchange, they would no longer have to make Ura Zelda.

In the game, there are unused cutscenes that show the Great Fairy training Link for his new abilities instead of just magically giving them to him.

Majora's Mask contains a reference to the Star Fox characters. The masks on the second row of the mask screen resemble the same animals that the Star Fox team is based on, including one of their enemies, a former member of their team who betrayed them.

In order:
• Keaton Mask = Fox
• Bremen Mask = Falco
• Bunny Hood = Peppy
• Don Gero's Mask = Slippy
• Mask of Scents = Pigma

During day 3 at the Romani Ranch, you can trigger a conversation where Romani tells you that that night is finally the night when she gets to drink Chateau Romani. According to the sisters, the properties of Chateau Romani are so potent that children aren't allowed to drink it under normal circumstances, drawing parallels with alcohol in the real world. It's also only served in the Milk Bar, where children aren't allowed, and is only open at night. The scene at the ranch unfolds with Cremia stating that she acknowledges Romani's adulthood, and asks her little sister to sleep in her bed tonight. Cremia dishearteningly utters "See you... Tomorrow... OK?" while Romani cheerfully adds "See you tomorrow!"

It seems as though Cremia knows that they're about to die, and is giving Romani the drink to dull her senses, so that she remains blissfully unaware of their destruction.

At the beginning of the game, you come across a warped dead Deku like figure. We can presume that this Deku scrub died in a horrible way. Additionally, later in the game, the Deku butler directly states that Link reminds him of his son, and he is seen weeping over the figure in the end credits. It's likely that this figure is the butler's son, and his spirit has been with you throughout the whole game.

After slashing a sign with your sword, playing the Song of Healing while near the sign will repair it. Once the song is finished, the solving a puzzle jingle plays and the sign magically repairs itself.

This same thing happens in Ocarina of Time with playing Zelda's Lullaby.

After receiving the Romani's Mask, if you protect Romani's Ranch from the invaders on the First Day, and help Cremia deliver the milk to Clock Town, you'll receive 1 of 3 rewards. Link can get either a Huge Rupee (worth 200 Rupees), some Chateau Romani, or a hug.

If Link receives the hug, Cremia will hold Link up close to herself and a message will appear saying "You did it! You helped Cremia!" "You feel all warm and fuzzy! inside! Sigh... You could get used to this!" The extra exclamation point after fuzzy was removed in later versions of the game.

The five main areas mirror the five stages of grief.

Clock Town is denial; its residents continue their daily lives refusing to believe the moon will fall.

Woodfall is anger; the Deku king is trying to kill a young monkey who allegedly kidnapped his daughter.

Snowhead is bargaining; Darmani begs Link to bring him back to life.

Great Bay is depression; Mikau dies trying to save the eggs of his love interest Lulu, leaving her alone.

Ikana Valley is acceptance; the only thing Link has left to conquer is himself, facing his own grief at the loss of his friend. The friend who began the journey, Navi.

In early versions of Majora's Mask, the moon had no face. This could be why some promotional art shows the moon with no face.

The Japanese version of Majora's Mask contained three save slots as opposed to the two that the American release saw. However, in the Japanese version, the owl saving feature did not exist, making the Song of Time the only way to save. This proved to be annoying and owl saving was added to the American release, at the cost of one save slot.

Majora's Mask has the least number of dungeons of any game in the Zelda series, containing only four on the main world. While there are technically four more on the moon, they are small, contain no bosses, and are completely optional, requiring a set number of happy masks to access each one.
