The Ankh is a backpack.
Unlike the other backpacks, the Ankh is more useful as a passive item, reviving the player for free upon death. Upon death, all enemies will die, color will be removed from the stage, and music is muted for the current stage. If the player presses the use button while holding the Ankh, they will be damaged.
How to acquire Edit
Bring the Ball to Sally and press use to enlarge the ball. Bounce the ball against Sally's face several times without letting the ball hit the ground. The Ankh will appear where the ball lands after you meet this requirement.
