Wubbzy struggles with stage-fright when performing with the Wubb Girlz. To help their friend, Daizy, Widget and Walden try several things, from Walden's hypnosis to Widget's invention, the Wow Wow 3000, but nothing works, especially when Widget's invention was the fake Wubbzy. The real Wubbzy then gets told by the Wubb Girlz that performing together is the best way to conquer stage-fright.
Wubbzy, Widget and Walden rehearse for a dance party at the Wubb Club. Daizy wants to join in but cannot play an instrument, and whenever she tries to tell Wubbzy what she can do, he gives her many chores instead. But when Wubbzy loses his voice after drinking all the lemonade, he and the others find Daizy, who sings very well. Daizy then jumps in and becomes the lead singer of the band.
Widget builds Wubbzy a Fire Engine. Later, when Chef Fritz is making pancakes on the top of a building, Wubbzy and Daizy mistake it for a fire to put out and Wubbzy gets stuck on top of the building. Daizy then calls out for help from Walden, Widget and the firefighters. The wind picks up, the tower tilts and Wubbzy falls, but the firefighters can rescue him in time.
Wubbzy makes a brand new friend, Daizy, who just moved into the neighborhood and wants to do girly activities with him. When a game of hide-and-seek unexpectedly takes Wubbzy to a kickety-kickball game, he realizes he misunderstood how to make good friends and make her feel welcome. Daizy makes new friends, Widget and Walden.
