Kingdom Hearts II/Hollow Bastion

When you first arrive at Hollow Bastion, a few Heartless will show up and send Sora, Donald, and Goofy searching for Leon and the others. After a little shopping and a visit to Scrooge McDuck's ice cream stand, you'll get in a battle with a few Heartless. Valor mode can take them out easily, but even without it the battle isn't hard. After some button mashing, you'll meet up with Yuffie.
