Harold and the Purple Crayon (TV series)

Harold is an adorably curious four year old with his purple crayon, who has the power to create a world of his own simply by drawing it. Harold 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. - IMDb
