Whilst doing some repairs in the Club House Todd accidentally knocks Drum's cuddly toy, Yapple, into his tool box and carries her off. Drum is distraught when she can't find Yapple and refuses to practise for the Big Zing. No matter how many silly things Zak does, Drum still doesn't cheer up.
Tang rushes to DJ Loose for help. DJ takes Tang to the glade where they see an orchestra. The orchestra plays the same bit of music in a slow sad way and then in a bouncy happy way. Tang realises the way the music is played makes him feel different and so rushes back to the Club House to play their Big Zing song in a different way in order to cheer Drum up. It works until Zak mentions Yapple, sending Drum into a very bad mood.
Once again Tang heads to DJ Loose for some advice. The Beach Byrds were also in a bad mood because of Todd's hammering and DJ has calmed them down by getting the orchestra to play some calm music. Tang rushes back to the Club House to play their music in a calm way. It works, again until Zak mentions Yapple again! Luckily Todd finds Yapple in his tool box and returns her to Drum. Drum is happy again just in time for the Big Zing.
