In this Bonus Stage, the player is sent to a small area with many Barrels containing variations of a type of item; for example, Extra Life Balloons and Animal Tokens. The item variations rotate throughout the Barrels and to successfully collect an item of the player's choice, the player must stop all of the Barrels on the same item, hence the name of the Bonus Stage. Upon doing so, that item will be released from the Barrels allowing the player to collect it.
If the player fails to select all of the same item, they lose and are sent back to the stage they were previously playing.
