Tripp is under pressure from the band to be nice to music producer's daughter Arlene so she'll pass their demo onto her dad, even though he doesn't fancy her, but a mistake leads to the band getting trapped in her high-tech house.

The band is working on a special song for a friend to use as his entry music for a martial arts championship, but when Tripp gets a new girlfriend he loses his inspiration.

The band is delighted when their old signature move, the Weasel Slap, becomes a worldwide viral hit - until a kid gets hurt. To quell the controversy they decide to write a song for the injured kid.

When invited to Arlene's house, the band uses the opportunity to impress her record-producing father.

Ash the drummer doesn't think the band appreciates him, so leaves to become a school janitor. The band auditions for a new drummer, but they come to realise how much they miss Ash.

Tripp has a problem. His mum is throwing him a kids' party with balloons etc. Iron Weasel have organised a raucous rock party. He ends up dashing from one to another so no-one's upset.
