Trivia

 * The ride is similar to that of Jimmy Neutron's Nicktoon Blast in various ways. For example:
 * During the queue, there are TVs around the entrance with Bubbles, Finn and Jake, and Alien explaining the Cartoon Network Studios rules in their own ways.
 * In the post-show, it shows various clips of characters that made supporting roles (like Adventure Time) and cameos (like Godzilla: Life on Monster Island and Eric and Claire) doing stuff after the events of Dexter's Blastastic Adventure.
 * This is the only ride in Retroland to feature modern-day Cartoon Network shows.
