The final product revolved around The Wattersons trying to cheer up Gumball, who was in an inexplicable bad mood. Gumball then gets mad and wishes for his family to disappear, which they and the rest of Elmore do. Throughout the course of the episode, Gumball slowly goes insane as he walks around the empty town. However, the original draft of the episode was excessively dark, with creator Ben Bocquelet mentioning it as the reason why the episode was considerably rewritten.
As of yet, details concerning the original draft haven't surfaced anywhere online and the only mention of it is on Bocquelet's Twitter in a conversation with one of the shows fans. 
In Brazil, that episode can be seen on netflix
