They can also be found in the Desert Subsurface underground layer as well as in Stone Caves and underground layers 0a, 1d, 3b, 5a and 5d. They can also be found in Ancient Vaults with electric, fire, and poison themes.
They can crawl on walls and ceilings, enabling them to move over any surface. Their primary attack is to dash at the player, revealing their underside and face.
This monster has a weakness (+50% damage taken) to Poison damage and a resistance (-50% damage taken) to Fire damage. Additionally, it cannot be inflicted with Burning.
Rare Form
A rare elemental variant of this monster can be found on bounty missions, and has a very small chance to appear in the wild. It has an identical drop pool, base stats, and spawn area, but applies the slowing Frost status effect when touched. This variant's underside appears to have a smiling face, instead of the normal variant's frowning face. 
This form can also be captured, and when caught will complete an entry in the Rare Pets collection.

Trivia
- The name Crustoise is possibly a portmanteau of "crust" and “tortoise”, likely referring to the spikes on its tortoise-like shell.
