Wubbzy, Widget and Walden get bored with their favorite things and Wuzzleburg itself. A man from Plaidville drives up and tells them about Plaidville, so the three friends decide to visit Plaidville.

When all the Plaidville residents find how "cool" it is to be a different color, Wubbzy, Widget, and Walden decide that Wuzzleburg is an exciting place after all.
The name is a parody of the phrase "The grass is always greener on the other side."
