this dolphin guy doesn’t exist, and never has.. but his legacy is near religiously talked about aboard the S.S. mammal, almost like he was the dear brother of each cetacean aboard. they call him... tweedlecat :] (chapter 2)
and those sprite tings, they’re called stallions. they kinda start kickin about from chapter 4 onwards. they’re nocturnal things that kinda fufil the biological niche of an owl, and have the hypermetabolism of a hummingbird. they’re extremely hungry and need to be eating almost constantly to sustain themselves, and they move incredibly fast but in a kind of erratic, twitchy vibrating way. on the ground you can hear their feet go PITIAPATAPITAPTPITPITIPIPIPIPPI .
they contain a loooooooooooot of energy... and their brains work extremely fast.
edit: Tweedlecat DID in fact exist. just isn’t present at all in his original physical form in chapter 2, he warps into something different entirely in chapter 3, kept alive by Captain Levythan’s delusions.
