SWITCH: Spider Stampede


Serum Which Instigates Total Cellular Hijack. The serum which can turn you into something else. Invented by Petty Potts – a completely crazy scientist who also happens to be Josh and Danny’s nutty next-door neighbour! When the twins sneak next door to find their runaway dog, Piddle, they accidentally run into Petty’s beastly serum! One stray squirt – and the twins find themselves with eight legs and the ability to shoot webbing out of their bums! Help! Now Josh and Danny are in BUG trouble. They must make a dangerous journey back across the garden in the hope that Petty can switch them back. But it’s a big bad world out there, and the brothers are no longer top of the food chain…

    This book was the best book I have read since feb 1. At first it seemed like an ordinary book about 2 kids but things changed towards the middle of the book. The storyline was brilliant !!! I rate this book @@@@/5.
