* ToyShip: Timothy x Yoko and Charles x Lily are practically canon. Claude x Grace could also be seen as this.
* ViewerSpeciesConfusion: Fritz. Is he a skunk? A badger? Nobody seems to be sure. Even looking at official reviews for the original Creator/RosemaryWells book that he appears in, ''[[http://www.amazon.com/Fritz-Mess-Fairy-Rosemary-Wells/dp/0803709811 Fritz and the Mess Fairy]]'' doesn't shed any light on the subject. Publisher's Weekly calls him a "skunk," Kirkus Reviews describes him as a "badger." Presumably, this applies to Miss Appleberry (the occasionally-seen student teacher) by extension, as she appears to be the exact same species as Fritz.
* TheWoobie: Yoko, both for the Franks breaking her taketomobo in "The Taketombo" (they later fix it) and for her Japanese family figures being stolen in "Lost and Found" (they're later returned, though it's not revealed who did it), to name just a couple reasons.
