Fight for the Quadrillion Dollars
In The Beginning, he is inside of a present that Spoony has given to Forky for his birthday. Forky opens the present up, and in it is Radio. He calls for 21 contestants to begin his show, then at the end, he asks the viewers to vote for 3 challenges.

In Plank Race, he determines what is going to be the first challenge. It was Plank Survival, but as everyone gets on the plank, he says he joked about it. The challenge that was voted the most was actually Obby Race. He destroyed the plank offscreen, which was brought up by Tea in episode 2.
