Synopsis:
Superboy begins a new hobby by collecting various rocks and minerals from other planets. He stores the items inside a hidden mountain cavern. When the mountain climbers come across the cave, they find Superboy's collection inside. They decide to leave him a gift of a rare mineral they have found.

Superboy returns to the cave only to discover that the gift left by the climbers is Kryptonite. Weakened by the Kryptonite, Superboy uses the rocks in his collection to rescue not only himself but the mountain climbers as well. Superboy then moves his collection to a safer location, inside an orbiting space platform.
