That makes no sense. Ax can't morph from human to lobster.
Not only that, but notice that Marco still has full human legs as a completed lobster, while Jake and Ax seemed to have lost the lower half of their bodies even though they're only partially morphed. It looks like they're being reflected from a mirror, but the placement of it is odd to be really sure.
Also, what is up with the old lady? She sees them morph from human to animal, and she would've likely been captured after that incident in the store, so their secret would've been blown way back at #5.
It's just a really badly made cover altogether, so I'm glad they went with the Gorilla one instead.
