Mission 66: Restore the town's Heartless

Mission 66 for Kingdom Hearts 358/2 Days sends Roxas to solve the mysterious disappearance of the Heartless population in Halloween Town.

Regular Mission
Restore the Town's Heartless by defeating the Leechgrave.

Story Summary
Roxas is sent to Halloween Town to find out what happened to the Heartless population, which leads him to an encounter with the Leechgrave Heartless that seems to "eat" other Heartless.

Challenge Mission
Completing this mission may take a few tries, as you not only have to rapidly take out both swarms of Tentaclaws, but also deal with the Leechgrave itself.

Like the timed mission, this one is a nusiance because you have to deal with three waves of enemies.
