Mole rat (Fallout Shelter)

Mole rats are creatures that appear in Fallout Shelter.

Characteristics
Mole rats are moderately tough enemies, beating radroaches in terms of strength, that can be encountered while sending vault dwellers out to explore the wastes, or uncommonly during vault incidents, in which a rush order has been failed. Mole rats are a bit more unique than radroach encounters, in that they will only spawn in rooms that are touching dirt; however, just as with radroach infestations, mole rats will spread to other rooms of the vault if not dealt with quickly enough, and will increase exponentially in number.

Just as with raider encounters, mole rats will also quickly drain the power in a vault.
