Dwebble (Japanese: イシズマイ Ishizumai) is a new / Bug - Rock type Pokémon introduced in Generation V. One is used in-game by Gym Leader Burgh. Dwebble is based on a hermit crab.
The shell for this shellfish Pokémon is a bit different, besides serving as a home it also serves as defense and protection. The Anime also shows that this Pokémon can leave its shell or abandon their old one to make a new and bigger one. Cilan has caught one.
Dwebble evolves into Crustle at level 34.
This Pokémon can easily melt holes in hard rocks with a liquid secreted from its mouth.
It makes a hole in a suitable rock. If that rock breaks, the Pokémon remains agitated until it locates a replacement.
Dwebble appears to be based off a Hermit Crab whilst Dwebble's name may be derived from the words "dwell" and "pebble".
No other Pokémon has the same egg group combination as Dwebble and its evolution Crustle.
