Mole rat (Fallout Shelter)

Mole rats are enemies found in Fallout Shelter.

Characteristics
Mole rats can be encountered exploring the wasteland and during incidents. They are stronger than radroaches and weaker than deathclaws. (They would only spawn in rooms that form the vaults boundaries - Until late 2018), but if not dealt with quickly they can move further in to the vault.

During incidents, mole rats will quickly drain the power in the vault. They will start appearing once one reaches 22 dwellers in their vault (in hardcore mode). Like radroaches, when spreading to other rooms, they will crawl back into the hole they came out of and then into the target room.

They can also be encountered during quests. Their boss variant (mole rat brood mother) is tougher, stronger and larger in size and has the ability to call for reinforcements. This ability is not very often used and can be interrupted.
