Mole rats

"Basically in baby country. Welcome to baby country."

Mole rats are hideous "little" rodent-monsters about the size of a fat baby human with roughly the same amount of hair. Individually, they are about as dangerous as an unarmed human. Their dangerousness grows exponentially with their numbers.

They are attracted to Mole Rat Repellant. "Repellant..."

The PCs battled a horde of mole rats outside the Fast Lane after they defeated the Nine Pins.
