A Blue Sea Salt is a medium-sized creature resembling a blue pot. Its lid is black with a small, conical, blue spike on it. The base of the pot is also black, with two short spikes on it. It has a short, blue, lightning-bolt shaped "wing" on either side of its body. Its large, red eyes take up most of the front of its body and are set in an angry expression. The Unversed insignia is on its back.
In Kingdom Hearts Birth by Sleep Final Mix, Blue Sea Salt receives a palette swap which gives them a lighter sky blue body.
The Blue Sea Salt Unversed is a master of Blizzard magic. It attacks by shooting ice shards at the player or dropping a single mass of Ice on the player. When its HP is low, it starts spinning on itself, creating a small tornado and freezing the player if they're unlucky enough to have contact with it in this state.
