Nobita uses Doraemon's Substitution Stickers gadget to substitute a phonebook for a manga that he needs to return to Suneo. He later uses the gadget to cause mischief until he substitutes himself for a mailbox to escape from his friends' wrath. However, this causes him to get locked out of his own house. Remade as Nobita Becomes a Sticker!? in the 2005 series.
