Squidge Dibley and his 6PU classmates at Craglands Primary are facing their biggest, grossest problem EVER.
When their beloved teacher, Ms Trigley, suffers a bizarre injury while watching aperformance at the school talent quest, Squidge's arch-nemesis (former-Vice-Principal-now-Janitor) Hector Hoovesly takes over teaching duties.
Hoovesly immediately locks Squidge in a padded room, transforms the entire Craglands South Primary teaching staff into phone-addicted zombies and seizes control of the school.
But Hoovesly plan for revenge is only just getting started. He won't stop until he has taken control of EVERYTHING.
Now, the only chance that Squidge, Padman and 6PU have to stop Hoovesly is buried deep under the school in an ancient, hidden bunker.
Can Squidge and 6PU save Craglands South Primary before their whole world literally collapses above their heads?
