Similar to Wubbzy's Big Movie!, the special is a compilation of four episodes from the series: "Wubb Girlz Rule", "Wuzzleburg Idol", "Wubbzy's Big Makeover" and "The Big Wuzzlewood Concert".

In "Wubb Girlz Rule", The Wubb Girlz, consisting of Shine, Shimmer and Sparkle, are the most popular singing group of all time, who live in Wuzzlewood (Hollywood), and everyone in Wuzzleburg loves them—everyone except Wubbzy, who doesn't know who they are. When it is announced that the Wubb Girlz are visiting Wuzzleburg, the townspeople plan a special welcome for them. However, when they go to the airport to see them, amusing that they’re flying to Wuzzleburg, they aren't there. Meanwhile, Wubbzy, who is unaware of the girls’ visit, arrives at the train station to see some trains, and it’s revealed that the girls have arrived by train instead of plane. Wubbzy thinks they've moved to Wuzzleburg, so he meets them and gives them a tour of the town. Back at the airport, the townspeople learn from the information booth that the girls are arriving by train, and they end up following Wubbzy and the girls all day. That night, they finally find them at the Wubb Club, where The Wubb Girlz announce that they will host the Wuzzleburg Idol Talent Show, the winner of which will fly with them back to Wuzzlewood to perform in their next concert. Wubbzy finally learns who they are. Though the welcome almost didn't go as planned, the girls tell everyone that Wubbzy is a great tour guide and they love Wuzzleburg. Then they all head inside the clubhouse for a party, in celebration of the girls’ arrival.

"Wuzzleburg Idol" takes place on the day of the Talent Show, where Wubbzy tries to find a talent he's good at, but can't do anything like the Wubb Girlz. The girls tell him to be himself and do whatever he does best, so he follows their advice. That night at the talent show, the Wubb Girlz are disappointed that most of the contestants are trying to emulate them. Wubbzy shows off an original talent and wins.

In "Wubbzy's Big Makeover", Wubbzy arrives in Wuzzlewood and has even brought Widget, Walden and Daizy with him on the trip. The Wubb Girlz show them the Wuzzlewood Bowl (Hollywood Bowl), where they will be performing the concert. The Wubb Girlz also introduce them to Stu, their agent, but when Stu meets Wubbzy, he tells him he doesn't “look like a star”, and needs a new look to fit into town. Wubbzy dresses in a hip-hop outfit, Stu gives him a trio of fellow hip-hop dancers, and changes his name to Wubb-Z “Z”. However, it causes Wubbzy to act too cool and he starts calling Widget, Walden and Daizy his old friends and abandons them. During the rehearsal for the concert, Wubbzy acts cool instead of acting like his old self, much to the Wubb Girlz’ dismay. While posing for pictures on his new motorcycle, Wubbzy accidentally turns it on, and flies up into the sky. He hangs his pants onto the edge of the Wuzzlewood Sign. He wants his fellow dancers to save him, but they refuse, stating he's “un-cool!”. Luckily, Widget, Walden and Daizy rescue him in the WubbCopter. Back at the Wuzzlewood Bowl (Hollywood Bowl), Wubbzy apologizes for changing and he reconciles with his friends. Stu wants to do more work with him, but Wubbzy refuses, so Stu shrugs, and is back to his old self. Then they head backstage to finish rehearsing, and the Wubb Girlz are also happy he's back to normal.

In "The Big Wuzzlewood Concert", it's the night of the concert. However, when famous news reporter Jann Starl (voiced by real-life Jann Carl)^[1] points out to Wubbzy he's going to perform in front of a huge audience, Wubbzy begins to have stage fright so his friends try to help cure his stage fright backstage before the show starts. The Wubb Girlz tell him they feel better whenever they have their friends around them so they invite Wubbzy's friends to perform with them in the concert. they accept, and they all deliver a great performance.

In between the special is also an animated music video for "Sing A Song", sung by Beyoncé herself.
