Capsule+ (also known as Capsule Boost) is a stage start item in Dr. Mario World. It gives players 5 extra capsules for use in stage mode. Free uses of this item could be rewarded from battle boxes or through certain events. If a player does not have any more free uses of this item, it requires spending 10 diamonds to use another. For timed stages, these items are replaced by Time+ boosters which are a separate type of item, so free uses of Capsule+ are not able to be used as a substitute. If a player fails a stage too many times in a row, Toad helps the player with a free use of it prior to version 2.0.0, while in subsequent versions the game would offer the player three of these items in diamonds for the price of two if the player did not complete the stage frequently. During a Power Boost Rally, players can use this item for free during the rally's period if they have beaten at least 3 stages in a row without losing or restarting.
