Wilf is a little boy who worries quite a lot about quite a lot of things. About almost everything. He's frightened of stuffed animals. Peanut butter makes him nervous. And as for the awful crawly insects that have waggly feeler-thingies instead of eyes? Well, that is just something that doesn't bear thinking about.
When The Most Evil Man in the World moves in right next door, Wilf is understandably alarmed. Panicked, in fact - totally and utterly freaked out. The neighbor, Alan, is a self-styled Evil Lunatic, with a grumpy robot sidekick and a dog named Kevin Phillips to prove it. Seriously, what kind of maniac gives his dog a surname? And why do the three of them always look like they're up to no good?
The only ally Wilf has in his desperate struggle to put a stop to Alan's ridiculous - but also quite upsetting, really, when you think about it - plans to destroy the world is his little sister, Dot (and her trusty "blanky", of course).
Could this be the end of the mighty worrier Wilf, or is it the beginning of a legend?
