Masami has a thicker outline, and Alan's face is drawn differently in this episode.
Many characters make a debut in this episode.
Gumball appears to have a square head and a tan jacket, while Darwin is much smaller, a darker shade of orange, his shoes are blue instead of green, and is animated with CGI.
It was uploaded to YouTube in 2010, but Cartoon Network took it down due to copyright reasons. On January 18, 2013, it was re-uploaded by Ben Bocquelet.
Ben Bocquelet said he might add the episode as a special feature on a possibly upcoming The Amazing World of Gumball DVD release if another one comes out, since it didn't make the first, second, or third one.
A link to Gumball's 2007-2008 designs that were used in this episode can be found below.
Nicky Jones, famous for the voice acting on the show Chowder as the titular character, voices Gumball in this episode, but in the actual series, Logan Grove does the voice of Gumball in Seasons 1, 2, and most of "The Kids," and Jacob Hopkins does the voice of Gumball in the ending of "The Kids," and Season 3 onwards.
In this episode, the opening credits are not shown. However, at the end of the episode, it simply says "Gumball" instead of "The Amazing World of Gumball." Also, the background of the credits is the sky instead of space.
In the shot where Gumball smiles at Darwin, the other characters in the background are missing.
If you look very closely in the scene where Tina is catching the steak, Leslie's petals change from blue to pink.
When Gumball and Darwin are launched at Hector's butt, Gumball disappears for a couple of split seconds.
[Almost the entire class and Rocky are in the playground, Gumball and Darwin are near the fence]
Gumball: Ok, buddy, today's day we're gonna break out school. [their plan is written on the ground] As you can see, I've simplified the plan. It is now foolproof! And you know what to do, right?
Darwin: Ready! Err... Ready for what?
Gumball: [sighs] Never mind. [whistles] Hey, T-Rex!! [throws a steak, Tina goes for it]
[Tina pulls on a rope tied to a merry go round that Carmen is on, causing it to go so fast that Carmen flies off, hitting and popping Alan, who is kissing Masami, making her cry on Leslie, making Rocky sneeze, the sneeze blowing Teri into the girl's bathroom, making the girls scream and throwing Teri into a wastebasket outside. The weight then causes the basket to be weighted down, which uses scissors to cut Ocho's web, who then jumps, accidentally, onto a trampoline, shooting him right into Banana Joe, who falls off the swing]
Banana Joe: [after falling on the floor] I'm Ok, I'm Ok! [Hector steps on him, causing him to slip backwards]
Gumball: Get ready to taste freedom!
[Hector slips onto the end of the catapult]
Gumball and Darwin: Woo hoo!
[They're catapulted but they crash onto Hector's butt]
Banana Joe: Hahaha!
Gumball: Eh, could've been worse.
[Hector tightens his butt, making Gumball and Darwin kiss each other]
