"wow! i can't believe how green the grass is over there. why isn't it brown like our side of the mountain" what step in the scientific method is this

the endomembrane system i think

fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
