* EarWorm: [[http://www.youtube.com/watch?v=GKUt5_NzFuE The theme song.]] And, oh so many of the other songs featured in the series.
* FridgeLogic: In "Kid Court," Peanut, Butter and Jelly miss an obvious potential solution to their problem - why don't they at least ''ask'' their friends if they can watch their shows at their houses, while Baby Butter stays home and watches ''Baby Lovey''? Do ''none'' of them have television?
* MercyKill: The show's seven years of being off the air.
* ViewerGenderConfusion: Butter is a girl. However, due to looking similar to her older brother "Peanut", people would tend to mistake her for a guy. Astute viewers, however, might have been able to figure out her gender from a line in the show's theme song - "Ooh, mother, father, ''sisters'' and brother," though unfortunately the closed-captioning is inconsistent in correctly transcribing this line. Of course, it didn't help that she was OneOfTheBoys - fond of playing in mud and enjoying boyish pursuits, preferring to spend her time with Peanut and his friends, rather than Jelly and her best friend Pinch.
* TheWoobie: Munchie Beaver.
