I bought the Ravenous Beast by Niamh Sharkey for the kids one Christmas and they requested it for their bedtime story for a very long time after that. What fun we had! They learned the story by heart and could do all the voices. Of course, they both insisted that they were the hungriest of all.
There is a version with an animated story DVD voiced by Kevin Whately, which I totally recommend if you can find it. (Kevin Whately is an English actor who plays the role of Robert “Robbie” Lewis in Inspector Morse).
