The first time the player and partner come through the mountain is during the events of Chapter 4, when Vice Principal Watchog tutors the children on looplets and emeras. Again, the students are separated into teams, this time consisting of the player, Deerling, and Espurr on one team; and the partner, Pancham, and Goomy on the other. The player again has their items removed and is given a group of selected items.
This is the second in a series of dungeons that cannot be revisited in the main storyline after they are completed. Subsequent visits must be made through Pelipper Island.
