This is a journal, telling the story of two ponies. The journal in question washed up in a plastic baggie on a beach. It has some pages missing; so the restorer searched for the ponies mentioned in the story. One, a Miss Ribbonetta Samantha Hearthus, was found to be deceased. Her grave is in the Crystal Empire. The other, a Mrs Chentella Amigo Sombrero, was found to be living happily in a rest home in Hoovesta Rica. She agreed to fill in the blanks of Miss Hearthus's story as best she could.
Breakwater Island. A resort off the coast of Marexico. When Sombrero and I are sent there, we see it as a harmless vacation. But what has Miss Rarity really have planned for us on this island?
