Would Merman Cas find himself packing on more weight than his vanilla counterpart thanks to mobility being less hindered underwater? Might take a good amount of time before he realizes his weight might be a problem... ——— good question!! he’d probably gain more weight because yeah, he should be more mobile underwater; although mobility is still an issue kind of because his tail is packed with so much fat it doesn’t move as great as it used to. and his stamina sucks lol
