The Underground Tunnels are an expanse of tunnels dug by Herbert P. Bear using his Earthquake Driller. The player must navigate through here in PSA Mission 8: Mysterious Tremors.

The tunnels are very dark and maze-like, and without a map and proper lightning equipment, it is very likely to get lost. The entrances to these tunnels are sealed after the mission ends. You need to go through six tunnels to reach the sunken Gift Shop.
