In New Carcinia, there are many cardboard boxes featuring a QR code. When scanned, it will link the player to a YouTube re-upload of a Rickroll-style meme called "You just got Coconut Mall'd", referencing a track from the game Mario Kart Wii.

Just before fighting Spoiler:Praya Dubia towards the end of the game, the background music that plays in the lead-up to the boss fight is a song titled "Crab Grave". The title of the song and its core notes (while not sharing the exact same melody) are a reference to "Crab Rave", a house song composed by Irish electronic music producer Noisestorm and accompanied by a CGI music video depicting crabs dancing on a remote island that later became a meme.

After passing through the Shallows and New Carcinia, Kril will enter an area called The Sands Between, an homage to The Lands Between, the main setting of the game Elden Ring.

The description for the Mason Jar shell reads "A simple container for storing everything from preserved food to cartoon figurines." Judging by social media posts made by the game's developer Aggro Crab Games, this is a reference to a meme where an anonymous user on the imageboard 4chan claimed to have filled a jar containing a figurine of Rainbow Dash from the animated series "My Little Pony: Friendship Is Magic" with semen.
