Kyle has a Derg form for a great reason: It's more awesome and not only that but it's because he ended up opening up to other Derg friends, though Kyle can still be ate in his Derg form, and the like. Even he can also bloat it a whole lot to make it bouncy. Trace realizes that Kyle has stuffed himself with a lot of food that way just as if he can be bounced around without accidentally crushing anything that is breakable, even though she may be against that idea, and Same goes for Ethan, but fusion can somewhat take a while to learn.
