What’s it about?

The story.

Struck by lightning one fateful night, Fergus and Shelby wake up with the power to transform into absolutely anything they can imagine: custard, a crisp packet, a giant plastic crab, you name it. It sounds like the best superpower ever, until a slug uprising begins and an evil slug masquerading as the Prime Minister sets out to turn the entire human race into lettuces. Now the two friends must master their ridiculous new abilities and save the world from a slime-covered takeover. Terrie Chilvers's madcap, joke-packed adventure races along with the kind of gross-out invention that hooks reluctant readers, brought to gleeful life by Brenda Figueroa's comic-strip illustrations. A short, punchy and very funny illustrated chapter book for readers who like their heroes shapeshifting and their villains slimy.
