The Wilderness Cave is a cave that appears in PSA Secret Missions. It was first used as shelter for the player in Mission 2, but Herbert P. Bear later uses it as a base. It is seemingly unoccupied at the moment, but it could have been the same base which was shown in Puffle Trouble, as the structure is similar. In PSA Mission 6: Questions for a Crab, the PSA Agent follows Klutzy down a skiing cliff. The player is back in the wilderness and follows the crab back to the cave. The cave has a door so the player relies on a black puffle to open it. Once inside the player is trapped and Herbert makes his first appearance. The player then escapes, after the mission Herbert abandons the cave since it is compromised.
