US Backcard Story
The ponies dressed in pirate clothes and gathered on Barnacle's ship for an exciting pirate party. When Barnacle landed at a tropical island, he gave each pony a treasure map. Slugger followed the map to a cave where he found a huge treasure chest! As Barnacle and the other ponies arrived at the cave, Slugger opened the chest and found a mound of golden coins. "They're pieces of chocolate wrapped in golden foil!" Slugger laughed with pleasure as Barnacle threw a handful of "treasure" into the air.
