Harold and the Purple Crayon

Harold is a curious four-year-old boy with his purple crayon who has the power to create a world of his own simply by drawing it. He wants to go for a walk in the moonlight, but there is no moon, so he draws one. He has nowhere to walk, so he draws a path. He has many adventures looking for his room, and in the end he draws his own house and bed and goes to sleep.
