- Peachy Teacher 3000 (final appearance)
Everyone in Wuzzleburg loves the Wubb Girlz. Everyone except Wubbzy, who doesn't even know who they are. When it's announced that the Wubb Girlz are coming to Wuzzleburg, everyone heads to the airport to meet them while Wubbzy goes to the train station to see some trains. Wubbzy meets the Wubb Girlz at the train station and gives them a tour of Wuzzleburg not knowing who they are or that everyone else in Wuzzleburg is trying to find them!
The Wubb Girlz (a three-girl band in the mold of Destiny's Child) are the hottest girl group in the nation with a hit Number One song on the charts. Everyone gets caught up in the Wubb Girlz craze. Everyone except Wubbzy, that is. He's more interested in watching the trains at Wuzzleburg Station. As everyone else in town is gathered at the airport to give the Girlz a big welcome, the planes finally arrives and much to everyone's surprise, the Kooky Kid comes out instead! Meanwhile, Wubbzy ends up being the only one around when the Girlz arrive instead on the Wuzzleburg Express. Having no idea who they are, Wubbzy happily offers to show them around and gives them a fun Wubbzy-style tour of Wuzzleburg - complete with runaway robots, spinney telescopes and gooey food explosions. When the townspeople finally catch up to Wubbzy and the Girlz who already cleaned themselves up at the Wubb Club, they're a little bummed that their big welcome ceremony was ruined because Wubbzy found them first. But the Wubb Girlz explain that Wubbzy gave them a great welcome and they had an AWESOME time! They also announce that they're hosting a talent show, called "Wuzzleburg Idol", and the winner gets to perform with them in their big concert in Wuzzlewood! So after a little sympathy, the Wubb Girls have their celebration in the Wubb Club, singing "Sing a Song"!
