See, Jawbone has an... "eating disorder". He eats things... like, everything. This is also why he's bigger than Dibbles. Dibbles is actually imune to pain and its unfortunate effects, is indigestable, and is also able to put himself back together... so, once Jawbone's done with whatever he's got his mouth on, Dibbles just has to wait, retrieve it, clean it (thuroughly, yuck) and put it back where it was. Convenient for him, but he's not as into it as Jawbone is...
