Bear is in charge of refreshments for the Woodland Valley Firefighter's Ball and Otto and Etta Otter have come to the Big Blue House to help out. As Bear heads to Mouse School to pick up Tutter, they work with Treelo, Pip and Pop to get things ready. At Mouse School, Tutter finds out that the mice kids are planning to do a dance called "The Mumble Mambo" at the ball --- one with which he's not familiar at all. At the movie theater, Ojo watches a classic film with Doc Hogg and gets her own idea of just what a ball should be like. When it comes time for the actual ball, neither have a good time, until Bear helps them to see past their expectations. Songs The Mumble Mambo Go with an Open Mind The Firefighter's Cha Cha Cha Notes This is one of the set of "leftover" fourth season episodes that aired in 2006, four years after the rest of the season. There is no Shadow segment in this episode. Harry and Mama Duck attend the Firefighter's Ball, although neither have any lines in this episode. "The Firefighter's Cha-Cha-Cha," is a send-up of "The Bear Cha-Cha-Cha" heard in many episodes. It features the same music and many of the same lines, but others are changed to be firefighter-related.
