Grandson decided to write a story. He enjoys actually writing the words but his inspiration was flowing too quickly for his penmanship, so he dictated it to his dad. He is, after all, only five.
To fully catch the atmosphere of this story, you have to pronounce the Ks in the names of the hero and secondary character: K-nooker and K-nacker.
He then illustrated it. The above picture shows Knooker - who is, incidentally, a hedgehog (that surprised you, didn't it?) - setting off from home with his anxious (hedgehog) mother saying goodbye to him.
This picture shows him being pursued by the dragon - whose cheerful expression shows that he thinks he's going to catch Knooker - the element of suspense - while Knooker's friend Knacker shouts encouragement from his upstairs window. And - here's the twist in the tail - it turns out that Knacker is a biscuit. Knacker the cracker, as Grandson himself told me.
(PS Please don't think I'm trying to suggest that he's a genius! I just think it's a hoot.)
