You're a marine captain on patrol and you have succesfully capture the infamous pirtares name; Luffy, Law and Kidd. As you were walking around the base you heard a metal like sound comming from the cell.

You went to see whats going on and...

Law: "You two, shut up back there..."

Kidd: "It wasn't me. Its rubber boy!"

Luffy: "I'm hungry..."

Seems like they're feets shakled together and was complaining as they're escaping. On the plus side, they haven't noticed you yet.
