The Challenge (Role Reversed version)

The kids play a wholesome game of kickball, all the while, Principal Prickly is being called by his brother, the other Principal Prickly. This Prickly decides to visit Third Street School to see how our Prickly is doing. Prickly then makes sure that the school is tidied up and ready for his brother's visit. Things are going well, just then, the other Prickly sees the game of dodge ball and challenges our Prickly to a game between their two teams. The kids express delight at a chance of missing school, and they wear purple and gold uniforms for the occasion. The other Prickly was fixing the school in a fashion similar to our Prickly just before the gang's arrives.

Gus separates from the group going past the school's own, Upside-Down Girl and Guru Kid. Gus then falls into a hole dug by the school's own diggers, much to their chagrin, and to Gus' fright. He tries to tell the gang, but he fails, and they do not find out about the school being an exact replica of their school, until they meet the other team, their own clones. They play the game, and each team is evenly matched (Even Gus and his clone both stink). This goes on for some time until T.J. negotiates with his clone, C.J., and the kids call it a draw, much to the Prickly brothers' displeasure. And while the kids go play on the clones' playground, the Prickly brothers fight until way past the end of the episode.
