In Best Fonds when Anne is in the thrift shop there is a tea pot and cup that look like mrs Potts and chip from beauty and the beast.
When Polly is eating the candy, a sound plays similar to the sound Pac-Man makes when he eats.
In "Anne or Beast?", the Plantars get around using a giant yellow slug that they dangle a leaf on a stick in front of. But in the rest of the series, they get around by a giant snail named Bessie.
