The Amazing World Of Gumball "The Rex" (partially found material of unfinished episode of animated series; 2012)
The Rex is an unreleased, 2012 episode of the Amazing World of Gumball. Its existence first came to light in 2012, when a complete list of episodes from season-two of the series was leaked online. Included in this list was The Rex.
As of 2020, very little about this episode has been released on the Internet, with the exception of a single storyboard on Jean Texier's website (alongside storyboards for the rest of the episode), which shows Tina Rex and her father attacking the titular character, Gumball, and a shot of a ravaged city. While the episode was never finished, elements of the story may have been reworked into the season 4 episode "The Routine".
According to series creator Ben Bocquelet via Twitter, it was "Too expensive and not worth the price."
