The Balloon Letter is an item that appears in Kingdom Hearts Birth by Sleep. When used, the Balloon Letter completely replenishes the D-Link gauge. It can be found in many treasure chests throughout various worlds or as an enemy drop from Unversed, as well as being sold in every Moogle Shop for 120 munny. The Balloon Letter was also useful because using a Dimension Link would grant the player a replenished HP gauge.
