troll gills

anonymous asked:

ok so my friend made a fantroll thats a seadweller that has cerulean blood and its really bugging me. she also gave them the ability to give other trolls the ability to breath underwater. i know this is all horribly marysue, but could you give me some facts as to why none of it would work?

Well for starters Cerulean bloods can’t be seadwellers, they’re too low on the spectrum. The ability to allow other to breathe underwater isn’t terribly unbelievable, as long as it isn’t something like they just snap their fingers and their bug can breathe in the ocean or make other trolls grow gills, those are kinda far out there. But if a troll could hypothetically make a bubble infused with psychic energy that others could use to breathe underwater, that would be fairly believable.
