Continuity mistake: When Filburt first reads his fortune cookie, it says "Bad luck and misfortune will infest your pathetic soul for all eternity". But later on when he is walking down the street it says "Bad luck and extreme misfortune will infest your pathetic soul for all eternity". (00:03:25 - 00:04:25)
Continuity mistake: Near the end of "Camera Shy," when Heffer gets the check out of the envelope, it's light blue. But when the shot changes it suddenly becomes black like the "censor bars" sticking on him and Filburt, so they obviously accidentaly used the wrong color.
Continuity mistake: In "Sucker for the Suck-o-matic," the TV opens up Rocko and Heffer's heads to scrub a weird product on their heads to make them buy the Suck-o-matic. The TV leaves their heads open when taking their brains out to dribble. In the next shot the heads are closed while the TV dribbles the brains. Then in the next shot, their heads are back open while the TV puts them back.
Continuity mistake: In "Trash-O-Madness," Rocko gets beaten up by the Trash dog. When Rocko goes back in his house, facing the screen his tail is fine, but in the next shot there is a huge bite mark in it. Then when he is in the kitchen, in the next shot, the bite mark disappears.
Continuity mistake: In "Bedfellows", when Heffer goes to bed he is only wearing his underwear. However, in one close-up shot during the sequence where Rocko tries to stop his loud snoring, specifically the portion where he uses a cattle prod, one of the purple straps of Heffer's overalls is over his shoulder.
