A Sucker For the Suck-O-Matic / Canned - S1-E8
Other mistake: A Sucker for the Suck-O-Matic: The Suck-O-Matic sucks in gunk from Rocko, Heffer, and Spunky's mouths and starts choking up. Then, when the Suck-O-Matic falls to the ground and passes out, the shadow of its head disappears mid-shot. (00:11:16)
Carnival Knowledge / Sand In Your Navel - S1-E9
Other mistake: [The episode will soon change to "Show Generally"] In the show's introduction, the giant clock comes and smashes a baseball cap on Rocko, growing him up. Then, when the giant blue hand picks him up, the baseball cap disappears mid-shot, with no explanation. (00:00:15)
Rocko's Happy Sack / Flu-In-U-Enza - S1-E11
Other mistake: Rocko's Happy Sack: When Rocko is shouting at Filbert in the checkout lane, as he says the line, "Beaten by a very large woman," we can see that his body is in front of the counter when it is supposed to be behind the counter. Part of his tail also turns blue for one frame. (00:10:54)
Clean Lovin' / Unbalanced Load - S1-E13
Other mistake: In the credits, Tom Kenny is credited for voicing Heffer, but Heffer does not make an appearance in either episode. (00:21:54)
Suggested correction: I think it's kind of nebulous whether or not this should count as a mistake. From what I gather, it's usually contractually stipulated (and sometimes enforced by union rule) that if you play a lead/regular character on a series, you're supposed to always appear in the credits, even if you miss a random episode here and there. As a result, this is actually relatively common. I almost feel like this would be better as a trivia entry. Or if these types of "meta"/fourth wall mistakes (credit errors, DVD box errors, etc.) had their own listing.
