It is the twenty-first episode in the series.
After overhearing Bashful singing in the shower, Queen Delightful insists on holding a concert to showcase his talent, so The 7D must find a way to help Bashful overcome his stage fright.
Queen Delightful is jogging through the forest with Lord Starchbottom and Sir Yipsalot. She then hears a wonderful singing voice and wants to find where it's coming from. They arrive at the 7D's cottage, and Delightful asks them who's singing; it's really Bashful in the shower. She then wants Bashful to appear at the Jollypalooza concert at the Jollywood Bowl (to replace Jenny Jollywood's spot because she literally has a frog in her thoat) and to showcase his talent. This makes The 7D laugh at this news nonstop towards nightfall and to the next day. When Bashful hears he's invited to appear on stage, he staunchly refuses and goes into hiding, prompting The 7D to look for him.
Starchy is urged to find a replacement now that Bashful is nowhere to be seen and recruits Sir Yipsalot after the dog show off his singing skills. Back at the cottage Bashful finally pops out of the dwarfs' couch, and reveals to his friends that he has stage fright and is afraid to go to Jollypalooza. It's also shown that he sings in his normal voice when he's out of the tub, but behind the curtain he sings beautifully in the style of Elvis Presley. However, he decided to appear at the concert as the dwarfs devised a plan to help him overcome his fear.
At Jollypalooza, after Sir Yipsalot (who appears as a flamenco dancer and sings) and Lord Starchbottom and Grumpy take the stage doing an Irish jig (to stall time so Bashful is ready to appear), it's Bashful's turn: The 7D brought the bathtub onto the stage and his singing amazed the crowd (with The 7D as his backing vocalists) and Queen Delightful, who is in attendance. He finally has enough confidence to perform another song—this time he out of the shower curtain and sings in front of Queen Delightful, still using his Elvis-style voice. After the concert, the Queen presented Bashful with roses and a kiss on the forehead, causing him to faint. Delightful also had enjoyed Grumpy's jig earlier and wants him and The 7D to appear at next year's Jollypalooza to tap dance, to his dismay.
