Which is not one of the three major types of rocks?

The three major types of rocks are sedimentary, metamorphic, and igneous. Did this help?

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.
