Smile

The Smile appears in the Item Shop in Wario Land 4. It is the only thing in the Item Shop that is free, but it has no purpose whatsoever. It is a joke item, and what the player gets is a smile from the shopkeeper Mr. Game and Watch. A sound effect also plays each time the player selects it.

All of the other items in the Item Shop are there to assist the player in defeating a boss. They all cost a certain amount of Frog Medals, which is the currency that is used in the game.
