Synopsis:
Krypto returns to Earth to play with Superboy. While playing with his dog, Superboy encounters a Kryptonite meteor and becomes trapped. He signals Krypto to bring help. The super dog locates circus owner Barney Blake nearby and brings him back to his master. Blake offers to help Superboy only if Superboy will perform in his circus. The Boy of Steel agrees, so Blake rescues him.

Superboy and Krypto then follow through with their promise to perform for Blake. Superboy is upset that the circus owner is charging customers large admission prices, so he intentionally causes damage during his stunts. Blake is forced to use his unfair earned profits to cover the repair costs. After multiple attempts to outsmart Superboy, Blake finally gives up.
