Douballoon Escape

What do you do when you find a giant's stash of enormous doubloons? If you're these Pirates, you strap some giant balloons to the doubloons and make douballoons!

 

Originally I wasn't planning to enter the Ideas Pirates contest, but I came up with this word pun and had to execute it. Thanks for looking!
