Biscuits, bands and very big plans

Summary/Review: "Tom has some very BIG plans! Tom and his band, The DogZombies, have some big plans! First they need to catch a glimpse into Delia's secret diary. But that'll mean taking a BIG risk: snooping in her room! Then they're going to write a new smash-hit single. (Which means stocking up on essential snacks.) Plus, Tom's got to doodle as much as possible, especially when Marcus is watching! It's lucky Tom's fuelled by biscuits, or he'd never have the energy for it all . . ."--
