My 3 and 4 year old daughters dissolved into fits of giggles at this one. It is a glove puppet inside a book (you operate it from the back). They just love the fact that Dudley leaps out of the book to talk, eat, sing, sneeze and snore at them, and that they choose what he does next. We have Calm Down Boris by the same author on order. If it's half as good I'll be pleased. Only downside is that the girls didn't rate Dudley's singing very highly . . . erm, maybe I should go and practice a bit more.
