Jonah and the Fobbalicious boys are forced to meet with youth worker Kool Kris after making bully videos. But when Jonah's brother is picked on, he gathers Year Seven rangas and attempts to make the ultimate bully video.

While grounded, Jonah and the Fobbalicious boys escape and go bowling. Their counselling session with Kool Kris leads to the boys taking part in the 'Feel Da Beat' song competition.

After a crazy day at school, Jonah and the boys embark on their biggest, most dangerous mission yet, but their plans backfire in a massive way.

Jonah's harsh new surrounds bring new opponents and some unexpected allies. But the pressure is mounting on family, fame and friendship.
