The Sweetstack (デリシャスタワー Derishasu Tawā?, lit. "Delicious Tower") is a Keyblade that can be wielded by Terra, Ventus, and Aqua in Kingdom Hearts Birth by Sleep and Kingdom Hearts Birth by Sleep Final Mix.
The Sweetstack is a Keyblade designed to look as if it is comprised of multiple scoops of ice cream stacked inside a clear bowl; Terra's version has six scoops, Ventus's has four, and Aqua's has five. The teeth are comprised of three orange slices splayed out. The hand guard is formed by two soft-serve ice cream cones on either side, connected by several metal ice cream scoopers. The Keychain is made of ice cream cones with a sundae as the token.
The Sweetstack's name references the typically sweet flavor of ice cream and the stacked scoops of ice cream that make up the Keyblade's shaft. The Japanese name, "Delicious Tower", carries the same meaning.
