Mission 68: Collect hearts
Eliminate Heartless in Agrabah and collect hearts.
Roxas is sent to Agrabah to collect hearts.
Patrol Agrabah and defeat Heartless to collect Heart Points. Locations of Emblem Heartless are scattered throughout the first two parts of the city, but are not hard to find. However, this mission cannot be completed 100% until Roxas has the High Jump LV3 ability, which is available by equipping the High Jump3 panel and two High Jump LV+(L) links, acquired later. This ability is required to reach the Heartless hidden on the raised north ledges of the Cave/Entrance Hall.
Once the High Jump LV3 ability is obtained, replay this mission from the Holo-Missions screen. Climb onto the overturned pink and gold column at the base of the north ledge. Position Roxas at the uppermost tip of the column, then jump over and grab the ledge. After defeating the Heartless up there, glide southeast to the raised platform across the cave, where a chest contains a Slide Dash3 panel. Now the mission gauge should be filled up to 100%.
