Rubberoid's Land



The Rubberoid's Land was the region of a planetoid that was inhabited by the Rubberoids.

This was geographically opposite of the region that the Crystalloids lived in.

Their land was subjected to much military attacks from the Crystalloids, and some of their people were taken away from their land and taken hostage and imprisoned in a guarded compound not to far from their fortress.

Superboy and Krypto came to this planetoid and rescued the Rubberoid hostages and destroyed the Crystalloid's fortress.
