“why give a seal legs/external ears?” not a seal (though really obviously based off of one), he’s a speciating werewolf from a sea ice type habitat
“qallupilluit/selkie/other mythological creature?” no, bargain basement dnd werewolf reskin
“crabeater teeth!” yeah kinda, but actually there’s a whole group of seals with lobed teeth you should check them out! my favourite seals are leopard seals and the overall long sleek body shape (minus legs) was more inspired by them.
“i want to pet him” he’s a grown man who hates being touched. he has a phd and teeth like a greenwood saw blade
