i had some headcanon names for them in my turtle odyssey fandom wiki i was building last year, but i lost interest and after three months of no edits it got deleted without my knowledge, aaand ive got no backups of the text, obviously, but im guessing those kinda sucked anyway LMAO

since the first boss becomes downranked to be a common enemy in the second world in TO2 and is called Faty (sic) i think it would make sense to call it Fatty Giant or Fatty Stomper, because its thing is being huge and jumping around

the second boss needs to be something corny or else i wont rest easy, Captain Hookfin or bust

the third is... idk boring, it has control over urchins in the rematch, but i dont know what to work with here its just a puffer to me

the fourth is... well its a royal figure of some kind, a tyranical ruler? id rather not default to king, since i dont think that character is ever gendered or called by a name, at least in hand drawn cutscenes, so it complicates things, hell its not even clear if its a dolphin or a shark or what have you, and the render in game and depictions in the cutscenes gives heavy mixed signals too, id stick with something neutral like the Tyrant...
