A good number of well-known video game characters make appearances, usually by parody or via easter eggs, in the game:

• There are a few Super Mario Bros references. One is a Wrestling event poster with the two brothers as a tag-team, another is an 8-bit Mario from Super Mario Bros for the NES patterned on a wall, and a sequence that ends with dropping a boss into a pit of lava by cutting the bridge off with an axe at the end, ala Super Mario Bros for the NES. The following scene has one of the antagonists telling the main character their "princess is in another castle." Two other more hidden references is the Goby Fish enemy hung up near the fishing town and a portrait of Booster from Super Mario RPG for the SNES.
• Donkey Kong appears with his trademark Barrel as a sort of stone pillar
• A statue of the Pokemon Squirtle can be found, standing on top of a stone Pokeball.
• A Luchador-version of Link can be found as a stained glass mural inside a church, as well as a number of posters found across the game. Another reference is an NPC's brother occasionally getting lost, apparently once getting lost in "some country where a kid in a green tunic was trying to stop some pig monster from being resurrected." The NPC's brother can be found, who is named ERROR, in reference to the NPC from Zelda II: The Adventure of Link sharing the same unusual name.
• Mega Man appearas as an 8-bit version of himself patterned on a wall and there is also an advertisement poster for his trademark E-Tank.
• There are a number of statues closely resembling Metroids, as well as "Chozoo" Statues which hold the players new abilities, ala the Chozo Statues from the Metroid series.
• There is a store called Viva Piñatas!, in reference to Rare's 2006 game Viva Piñata.
• A statue of a Cactuar from the Final Fantasy series can be found in the desert.
• A couple of Castlevania references can be found, one of which is a poster of a match between a parodied version of Simon Belmont and Dracula, the other is an etching of a more 8-bit version of Simon Belmont fighting a Skeleton with his whip.
• A Space Invader shaped by moss can be occasionally found in one of the temples.
• A wall etching of Q*bert can be found in a hidden area.
• Outside of the first town, a poster says "El Destructo Vs. La Bomba" can be seen, a reference to gaming websites Destructoid and Giant Bomb, respectively.
• In the desert, there is a poster for Bust-it Bill, a reference to Wreck-It Ralph.
