Mini-Kit Detector.

-This MUST be done in free play. This is located where you find R2 in the normal story
mode. When you go through the first Bounty Hunter Door (after beating Boba Fett), turn to
the left down the hall. Go all the way to the end of the hall. Once at the end of the hall
exit the door to the right. When you get out onto the platform, the block will be sitting
on the back of the Slave I.
