Laura explains that her father used to work at the old Cartoon Network studios, and why this projector was given to him as a gift for his hard work. They decided to turn it on, where HIM laughs and appeared in front of them. The six teenagers ended up getting transported by HIM to the different universes of the CN multiverse.

Trivia

 * When the Eds mentioned their trip outside of Peach Creek to find an ancient cast in the sky, they were mentioning the events of Ed, Edd n Eddy the Movie: The Ed-Touchables.
 * Unlike the other cartoon characters, Tom and Jerry don't have bigger roles in the film, so they both have a brief on-screen cameo where they chase each other.
