Mission walkthrough
Proceed to the Bizarre Room to encounter the targets.

Challenge Mission
As there are not one, but two Crimson Pranksters, this mission will be even more difficult. The main thing is to keep track of both Heartless and watch their attacks. As your HP drains when on the ground, this will largely be an aerial battle. Glide is a necessity as you can stay in the air for a longer period of time, losing less health.

This mission can be a nuisance due to the fact that the Crimson Pranksters can revive each other if not taken out in quick succession. Thus, you'll have to alternate between them. Stay in the air as much as possible, use your Limit Break when you can, and bring Aero Magic, as it is most effective against them.
