"The Other Guy" eating cereal.

The Cereal first appeared in the episode Make Da Band and was later seen in Happy Winter Friends (Part 2). It makes people become green for a short time, but it is unknown why.

In Make Da Band, after Baman and Piderman finished singing a song (which became the show's title theme) Piderman looked confused, so he went to go eat some cereal to help with his confusion. While he was eating cereal, Piderman turned green, but he only realized it after Baman brought it up.

In Happy Winter Friends (Part 2), Those Guys appeared to be having a wild party. The Other Guy was eating cereal, and also became green.
