Klefckle loves collecting keys and will go to extreme lengths to obtain them. It is so protective of its keys, it stores them in its rock-hard shell to protect them from thieves like Murkrow.

A Klefckle hides under rocks, keeping its body concealed inside its shell while eating stored berries. It never lets go of a key that it likes, so people give it the keys to vaults and safes as a way to prevent crime.
