In "Pig Amok", Brunnhilda, Pig's arranged wife, is always seen berating and insulting Pig (who is too love struck to care) with no redeeming qualities to boot, but it's when she laughs at Otis' supposed death by "broccoli poisoning" that you know she's over the line.
Winky the ghost rabbit pretty much trying to fling the protagonists into Hell for exorcising his fellow ghost pets and declaring that if he can't have their bodies then they can't either. Fortunately, Otis comes in to save the day.
The cover of ''"Cowman: The Uddered Avenger"''◊. Yes, we know it's a kid's show and it's obviously a spoof of a dramatic superhero comic book cover, but there's something so over-the-top corny about it that it hurts to look at it.
Farmer Clem only returned in an episode towards the end of the series.
They Wasted a Perfectly Good Plot: Many fans were extremely disappointed about the show not depicting an episode where Dag returns to get his revenge on Otis, and therefore that story only exists in Fanfiction.
Uncanny Valley: The animation of the TV series can be considered rather... odd. Especially when compared to the much more fluent animation of the film it was based on.
