Enforced Method Acting: In "Shard at Work", Warren Graff choked himself with water while recording the scene where Handy gets a fish bowl stuck on his head.
Missing Episode: Several "irregular" episodes can't be found on Mondo Media's website. Among them are "Dino-Sore Days" (a sketch featuring a non-ice-encased Cro-Marmot), "Intimate Spotlight" (an "interview" with Cro-Marmot), Cuddles's "Smoochie" episode, and a Christmas episode titled "We Wish You".
Giggles, Petunia and Cub have always shared a voice actor, though the role has been replaced twice: first Dana Belben, then Ellenn Connell, now Lori Jee.
David Winn replaced Rhode Montijo as both Lumpy and Splendid when Rhode left the show. Similarly, Kenn Navarro replaced Mark Giambruno as both Lifty and Shifty (although Giambruno's laughs were sampled in at least one episode) and Francis Carr replaced Jeff Biancalana as Russell.
Kenn Navarro voiced Handy in "A Hole Lotta Love" because Warren Graff was unavailable.
Subverted with Pop; Aubrey Ankrum's voice has been sampled since he left the show. Ankrum is also sampled for evil Flippy, but Kenn took over voicing good Flippy.
