Exactly. Quite a few of the League champion skins make no sense given their lore, but they still work with the champions. Walrus Abomination makes a certain amount of sense.
EDIT: Just had an idea. I think it should be Werewalrus Abomination, where during the day, he looks completely normal, as well as on the splash. As soon as it turns night, though, he should turn into a walrus.
