The Pokemon Red and Blue Release

The Pokémon Red and Blue Release was planned to be an episode of Season 4 (1998).

In Late 1997/Early 1998, while Season 4 was being worked on, a company called Game Freak wanted them to make an episode about their new games, Pokémon Red and Blue. The Greeny Phatom Team thought the game would sell horribly so they cancelled it in the writing stage. Not wanting to have a gap in their Season 4 episodes, they replaced it with Little Guy Tortures The World. After Season 4 aired and Pokémon Red and Blue released in North America, Pokémon Red and Blue sold more than 31 Million units, James Clayton (who was in charge of writing the episode) said "This was probably the biggest mistake I ever made while working on Greeny Phatom.)
