Upon entering the gym, the player will see a giant stalagmite in the center of the room. At the back are two benches the player can sit on to have a view of a waterfall in the back which also has a rainbow. Here, the player must climb up specific walls to reach the Gym Leader, who resides at the top. There are blue panels on the floors which the player must stand on and get off of to proceed. Along the way, the player must face four trainers before reaching the top. Behind the gym leader is two sets of stairs leading to a climbing wall. Below this are two slides to reach the bottom.
