Monster Bogey

Monster Bogey is a children's book for, I would say, seven plus. And it's about a little boy called Frank who picks his nose. He makes a tower out of his bogeys and he lives in a castle. One day the tower gets struck by lightning and turns into a bogey monster. It's like Frankenstein meets bogeys, you could say. An adventure that takes place in the castle and somebody who wants to steal the castle. The illustrator is a guy called Owen Lindsay, who's Australian.
