Mummy Form

When Sora, Donald and Goofy visit Halloween Town, Donald's appearance is altered to one that resembles a mummy. His entire body is covered by mummy-like bandages, and a gap between his stomach and waist reveal that there is nothing under them. A similar gap is located between his left elbow and wrist. Donald's beak and feet become less vibrant in colour, and his eyes gain a thick, black outline around them (thus giving the impression of an actual Egyptian).

In this form, all abilities learned previously by Donald can be used with no negative or positive effect on them.

In Kingdom Hearts II, his magic staff is covered in dust as a way to blend in to the design of Halloween decorations.
