Operation: B.R.E.A.K.U.P. Codename: Kids Next Door : Season 5 Episode 6

Wallabee Beetles is charged with protecting his mom's prized/priceless koala bear vase, or he'll have to go to Ballroom Dancing School for ballroom dancing lessons. This becomes increasingly hard as the vase is stolen. He follows the robber, which takes him to a base ball stadium and used for a baseball-like game called "Vaseball", where kids use glass and pottery as the balls. Numbuh 4 thinks he must play, and turns out to be very good. But then, the pitcher throws the vase he was supposed to protect. He tries to get away with the vase, only to find himself in a room of bullies. In the office, Wallabee uncovers an insidious plot by his old friend turned enemy Ernest (the commissioner of Vaseball) and his band of bullies, who plan to rat the kids out for their misbehavior, so they can get the kids grounded that way no one can tattle on them as they vandalize every house in the neighborhood. He accidentally knocks over a bookshelf -- "Uhh... Does that count as a home run?" He gets away, only to find himself in a match to the death with Ernest. They duel with plates, vases, and all sorts of breakable china. The only thing they don't destroy is the vase Wallabee is supposed to protect. Finally, he knocks a bookcase on Ernest, knocking him out cold. He saves the vase, but the other bullies have already carried out their plan. Every kid (including Ernest) is grounded except for Wallabee. "He will always live in the hearts of kids who love to break things." As the screen goes black, we can hear the vase finally breaking and his mother angrily screaming "WALLABEE!". It's unknown if she follows through with her earlier threat.
