The Super Cheerleader Box is a special type of rescue, available from February 1, 2013 to February 5, 2013. Because it is not explicitly named a rescue, it is available through the store rather than the rescue page; however, all of its contents are pirates, and could thus be classified as a rescue.
Each Super Cheerleader Box costs 499 gold coins and contains exactly 1 pirate each. Pirates currently available from the Super Cheerleader Box:
