The episode "Leap Frogs" was banned from Nickelodeon due to subtle sexual innuendo (and a scene where a spider is on the toilet). However, it was revived when it aired on Nicktoons TV.
In the beginning of the episode, "Bedfellows," Heffer's parents are watching an episode of the TV show, "The Odd Couple," which is what Heffer and Rocko become.
The opening intro is a bit faster paced than usual.
Originally aired as the sixth episode on October 31, 1993, but instead aired as the second season on September 19, 1993.
