Vault 81 lab mole rat

 is a creature in Fallout 4.

Characteristics
These mole rats were initially used to test the spread of pathogens in Vault 81, but after the secret section of the vault failed, the mole rats took over. They have the unique abilty to transmit mole rat disease, which incurs a permanent -10 penalty to hit points unless the Vault 81 cure is used.

Appearances
