Swimming

Swimming is a form of movement that appears in Kingdom Hearts, Kingdom Hearts Final Mix, Kingdom Hearts II, Kingdom Hearts II Final Mix+, Kingdom Hearts Birth by Sleep, and Kingdom Hearts Birth by Sleep Final Mix.

Surface swimming appears first in Kingdom Hearts, requiring Sora to swim out into the ocean to collect fish for Kairi and Kingdom Hearts Birth by Sleep — essentially, the character will swim around in the water in a breast-stroke style. They cannot jump, so they must get to a shore in order to get out of the water. In Kingdom Hearts Birth by Sleep Terra, Ventus, and Aqua can swim faster by holding and in Kingdom Hearts, after he learns Mermaid Kick, Sora can swim faster by holding.

In Kingdom Hearts and Kingdom Hearts II, Sora can swim in all three-dimensions while in Merman Form at Atlantica.

In Kingdom Hearts Birth by Sleep, the only form of swimming can be used at Neverland. However in the Final Mix version, swimming is also in the Mirage Arena match against Monstro.
