** Also, Timmy the Frog Kid is a baby in this episode, but in others he is old enough to speak, walk, and wear underpants instead of diapers.
* In "The Founder", everyone thinks Richard is the long-lost founder of Chanax, and even had scheduled a reunion with him. The actual founder is Mr. Chanax, who died in "The Boss", and everyone knew about his death. The soulless office worker, Paperball, and the green goblin CEO, who appeared in “The Boss” and knew all about Mr. Chanax’s death, were in this episode too and believed Richard was the founder.
* In “The Understanding” Quattro and Siciliana don’t know what the internet is, but just a few episodes before, “The Intelligence”, they, like the rest of the town, go insane without the internet.
* In “The Faith”, Peggy and the octopus kid are Boy Scouts despite both being girls.

* In "The Ghouls" Alan and Leslie have no idea of what a VHS tape is, but in "The Saint", Gumball shows him a video tape and he doesn't question what it is.

* Darwin says Marvin is a "ninety-something guy" in "The Faith", while he was referred to as an octogenarian by Hank in "The Watch". Either or both of these could be just assumptions.

* The Moon is male in some episodes ("The End", "The World", "The Night"), female in others ("The Love", "The Boredom", "The Box").

* "The Others" shows that Gumball and Darwin thought the entire school only had their class before they saw other students for the first time. In many previous episodes, however, they notice and interact with students outside their class; the entire premise of "The Extras" in season three was Gumball and Darwin being told that there are more people around them, and telling them to notice, which happens again in "The Others".

* In “The Slide”, Green Bear is on Trawlr despite being in junior high, and is portrayed as a girl while in "The Extras" he clearly has a male voice. Rocky and him get matched and Rocky even refers to him as her. Although it could’ve been a female using his picture as her profile picture. It could also be his mother if she is identical to her son and divorced/is cheating on her husband.
