Inspiration for the show's characters:
Hey Rock! Do that goofy face you do when you're buying eggs!
Animation error: When Rocko is wearing his normal shirt, he is wearing nothing below his waist. He clearly has no pants/underpants of any sort on. But whenever his shirt is removed, he GAINS a pair of underpants.
For a while, Nickelodeon pulled the episodes "Leap Frogs" out of circulation due to sexual innuendo, and paired the cartoon that it originally aired with, "Bedfellows", with "Wallaby on Wheels". As a result, the cartoon that "Wallaby on Wheels" was originally broadcast with, "Heff in a Handbasket", was also temporarily pulled from the network.
