Very strange. I haven't seen this before. I'm working with a bunch of children's books from our "PM Resources" series, and one--"The Race to Green End"--tells the story of characters on one of those "stuck in the mud, stay until you roll a three," "You are lost, go back to 24" games. The strange thing is, it's told third-person from the point of view of the characters in this strange world.

"I don't think that I can catch up to the shiny motorbike now," she said, "but I'll try." Her next throw was a 5. "That's good! I can go along the short cut," said the red bus. Then she threw a 2.

The shiny motorbike had missed three turns, and he looked down the road. The red bus was only a little way behind him!

Peculiar. The pictures show streets, paths and trails with the numbers of the spaces picked out on them. It's rather "Through the Looking-Glass"-y. Or like a particularly badly-played RPG.
