Underneath the pet store, generations of wild rats have formed a complex system of tunnels in the foundation of the store. There are several openings into the above-ground areas of the store, allowing wild rats to steal supplies as necessary.

After the flood, many of the tunnels have been destroyed. The wild colony devotes lots of its time to rebuilding these tunnels and burrows. Some of the worst areas are still filled with corpses of the dead, so this is not a pleasant task.

The entrances to the underground tunnel are located near the dog kennels, underneath the check-out counter, and through a floor drain in the quarantine room. At present, two of these entrances are blocked off, leaving the dog kennel area your only access to the above-ground.
