Book 4 in the Toby and the Pixies series

Toby is trying his best to reinvent himself as 'T-train', the coolest boy in school, and the pixies are keen to help... but every time they do, things go very wrong.

From giving Toby a 'fresh start' at school by erasing everyone's memories - including his Dad's and his best friend Mo's - to mixing up their magical size-changing powder on Toby's spot causing it to grow GIGANTIC, the pixies seem to wreak havoc wherever they go!
