Dwebble resemble an orange hermit crab, with large pincers and dark, oval-shaped eyes supported by eye stalks. It has a hook-like tail that is concealed underneath the sectioned chunk of gray rock it uses as a shell. This tail is possibly used to keep the rock in place or to carve itself a new home should its old rock get lost.
Dwebble live in the desert. Dwebble is able to expel a corrosive spray from its mouth that helps dissolve, as well as mend rocks. It uses this ability to carve out a shell for itself or to repair fractures in the shell.
Dwebble first inspect a rock to see if it could be used as a suitable shell, then dig a hole in the rock's bottom, to use as a protective shell. Dwebble can make rock easier to carve by producing a liquid from their mouth. When done, they appear to use their hook-like tails to grapple onto it. If the rock where it lives breaks, it won't calm down until it can find another rock to replace it. [Source: Bulbapedia]
