Dolly, Hayley and Marco get a taste for trouble when they realise just how much fun being bad can be. Tracy thinks they're clueless and brags about all her famous scams – cheese sauce in wellies, running round the garden with the head care workers knickers on your head and eating a worm, to name a few! The little kids are in awe and decide to set up 'The Beaker Club'. However, The Beaker Club's actions nearly cost Dolly her soon-to-be foster family. When the foster family in question turn up at The Dumping Ground and the Club drop ketchup-and-flour bombs on their heads, not realising it's Dolly's soon-to-be foster family, their actions soon bite Dolly on the bum.
