A little boy receives from an old magician a magic pencil and eraser: everything he draws with the pencil becomes real and everything he erases with the eraser immediately disappears into reality. The little boy used the magic gum to erase his two friends as well as his dog and finally the sun. The next day, the sun did not rise and the darkness was total. The boy was remorseful and looked for his pencil to draw the sun but could not find it since it was dark and there was no one left to help him.
