Tortoise Form

Tortoise Form is the form Goofy takes as a tropical tortoise when he visits the Pride Lands with Sora and Donald. Like his Turtle Form in Atlantica, the only familiar part left of him is his head. The rest of body is merely that of a yellow tortoise, which also is an underlined reference to his defensive abilities, since he is represented by a defensive animal.

Unlike his other forms, Goofy fights by spinning around and he also runs by doing this; his combo attacks are comopletely unavailable.

''Captain of the Royal Knights. He's traveling the worlds with Sora and Donald in search of the King.''

Goofy's been transformed into a turtle in this world, and it seems to suit him just fine.
