* EarWorm: The theme song.
* {{Moe}}: '''Moosel''' and to a somewhat lesser extent, Butterbear.
* NightmareFuel: "Bumblelion and the Terrified Forest" is full of it. The episode's a freaking ''horror movie pastiche'', for crying out loud! Perhaps the worst of it is when Bumblelion and Hoppo come across the sign directing intruders to the vampire-witch's castle; the trees sprout the most ghastly {{Nightmare Face}}s and start wailing about how they should run away, with a chorus of spine-chilling ghostly moans.
* UnintentionalPeriodPiece: The theme song, from the very. First. Freaking. CHORD!
* TheWoobie: Moosel. Especially in the episodes Horray For Hollywuz and Moosel's Monster. In the Hollywuz episode, Hoppo pretty much treats the poor little guy as a doormat and in Moosel's Monster, the other Wuzzles yell at him for his over active imagination causing him to slowly waddle home. With tears in his eyes, Moosel laments that no one would want to be his friend with his overactive imagination and that he's his only best friend. This scene just makes you want to reach into your screen and give the poor moose-seal hybrid a good cuddle.
** JerkassWoobie: Rhinokey becomes this in "Pests For A Pet".
