S.W.I.T.C.H.

Josh and Danny are in bug trouble when their next-door neighbour Petty Potts, a mad scientist with a beastly serum, squirts them with her S.W.I.T.C.H. spray!In 'Spider Stampede', the twins find themselves with eight legs and the ability to shoot webbing out of their bums, while in 'Fly Frenzy' the boys end up with wings, 360 degree vision, and a strange attraction to dog poo!

Two brothers, one serum, and a world of trouble! In 'Ant Attack', the twins are horrified when they are accidentally turned into ants: can they escape before terrible Tarquin roasts them under his magnifying glass? 'Crane Fly Crash' finds Josh and Danny going on a rescue mission to save their annoying big sister, Jenny, after she accidentally uses the S.W.I.T.C.H spray and turns into a crane fly!

Petty Potts' most recent repto SWITCH spray doesn't seem to be working… not that Josh and Danny were all that excited about being chameleons anyway - alligators would be way better! Plus, they're distracted by the mystery of who is sending them clues to find marbles filled with scientific code. But at school the next day, time seems to be going too fast for the twins, and when one of Danny's eyeballs rolls right round in its socket, they know things are getting weird. How long will it be before the boys are boys again?

Josh and Danny are on holiday with their parents in Cornwall - so the last person they expect to see is mad scientist, and next door neighbour, Petty Potts! So when the twins see her on the beach - holding a turtle under each arm - they can't help but wonder what she's up to. The thing is, the boys have got other things on their mind. They've found another mystery marble clue, and need to get out to the ruined fort on the rocky island. But they take too long and the tide comes in, trapping them.

Petty Potts has vanished - at least it seems that way to Josh and Danny. In actual fact, she's just relocated her secret lab… to the very pink and very girly Princess Land! Reluctantly, the twins fight their way through hordes of excited girls dressed as fairies to the back of the shop, where a single door stands between them and Petty's new lab. SWITCH-ing into geckos, the boys have no problems getting under the door and up the walls. It's on the way out that things start to get really tricky.…

Josh and Danny have gone for a nice day out at the zoo. Or, should that be, a nice, experimental day out at the zoo? Petty's developed a new S.W.I.T.C.H. spray for snakes! And Josh and Danny are willing volunteers. Things start to go a bit wrong though when they fail to SWITCH back into boys, and are spotted by a whole class of girls on a school trip! Luckily, Charlie, an old friend from summer camp, is there to help, and the panic subsides. The trouble is not over yet though....

Petty's been kidnapped! Josh and Danny have already broken into her secret lab looking for her, and now they're going to brave all her anti-intruder traps and break into her house. There's no sign of Petty, but there is a very interesting little box…containing the best SWITCH spray ever.

Unable to resist the temptation, the twins head to the park to try out alligator SWITCH spray. But before they make it to the river, they're roped into being in the audience of a touring chat show, with some VERY interesting guests...

Oh no! Mad scientist Petty Potts just turned up at Josh and Danny's Summer Camp, as the new camp counsellor. And she just happens to be hiding some bottles of extraordinary serum inside her raincoat... That can turn them into amphibians! Josh and Danny vow to stay away from Petty's SWITCH formula, but when their new friend Pippa gets into trouble, they know there’s only one thing for it.
