Barp may not be able to run fast, curl into a ball, or cure his hair loss, but he does have one thing that sets him apart from other precision platformer characters. During the Sage Challenges, Barp has access to an orb, this orb is the only way he can deal any damage to any of the enemies found in the levels. It can also be used to interact with certain stage elements, as well as defend Barp from projectile attacks. It's so important that you cannot progress to other rooms without having the orb in your possession.
