Fragile, Splatty, and the Purple Guy are in this episode but were scrapped in the final series. The name originated by Bocquelet thinking of things a child would randomly have in his pocket. Also, the background of the credits is the sky instead of space (which may imply that the show was originally intended to simply be titled Gumball). However, at the end of the episode, it simply says Gumball instead of The Amazing World of Gumball. In this episode, the opening credits are not shown. Darwin's CGI model can be seen in the background of the Void in the episode of the same name. Darwin bears a slight resemblance to Nemo from the movie Finding Nemo.
Also, it may be implied that he is a student rather than a custodian, which he is in the series. Rocky appears to have an allergic reaction to pollen. Gumball appears to be very intelligent in this video, judging by the plan drawn out in chalk. Ben Bocquelet uploaded the video to his Twitter, two years after it was created. It was also implied when Teri was blown under the girls' bathroom, and the girls screamed. According to the plan drawn in chalk by Gumball, Teri was originally a boy. This idea may have been reused in "The Storm.". In this episode, Masami kisses Alan (who does not object), but in the actual series, it has been shown that Carmen and Alan love each other. Jake Pratt also voices Darwin in this episode. However, in the actual series, Logan Grove does the voice of Gumball in Seasons 1-2, and most of "The Kids," Jacob Hopkins does the voice of Gumball in the ending of "The Kids," Seasons 3-4, and most of "The Copycats," and Nicolas Cantu does the voice of Gumball in the ending of "The Copycats," from Season 5 onwards. Nicky Jones, famous for the voice acting on the show Chowder as the titular character, voices Gumball in this episode. A link to Gumball's 2007-2008 designs that were used in this episode can be found below. Many characters use old designs in this episode, making this, "The Mystery", "The Curse", "The Joy", and "The Void" the only episodes in which characters use old designs.
