Sonny Muslim and Jay Haher play brothers Ryan and Zac Patterson.

Tracy tries to escape the Dumping Ground and makes friends with a boy called Ben who claims he's living on the streets.

Notes: Tracy goes head-to-head with Justine in a game of dares so that she can win back her old bedroom.

Notes: After Louise chooses Justine over her, a miserable Tracy meets Ben again and smuggles him into the DG.

Meanwhile, Duke is having problems with mice in his kitchen and plots to hunt them down, whilst Zac and Ryan try to stop him.

Everyone attends his party, except Tracy, who is secretly looking after two giant African land snails for the weekend.

Later that night, the snails escape and everyone is secretly roaming the corridors of the DG - including Peter, who has run away from his new life before it has even begun.

In spring 2003, four episodes of Series 1 were repeated as part of BBC Two's weekday morning strand on educational programmes for schools.
