Mission 47: Collect hearts
Eliminate Heartless in this new world and collect hearts.
Roxas visits Wonderland, a confusing and mysterious world, for the first time, on a heart-collecting mission.
Jump on the ledge to the left of the chimney and take down the two Striped Arias. From there jump on the table in the center to encounter two Sapphire Elegies. Now, go to the south-west corner and fight the two Grey Caprices.
Now, once you see the moving chair, head over there and attack it to reveal the Lurk Lizard. Once it is defeated, your mission is complete. You can collect any treasures and the Unity Badge any time before you RTC.
