When Rainbow Dash invites Captain Celaeno and her crew to visit her hometown of Cloudsdale, the pirates gladly accept. They have a blast visiting Rainbow Dash, but a trip to a boring old museum isn’t exactly their idea of a good time. That is until they come to a glass case with a replica of an ancient Pegasus relic that supposedly created an unending good fortune for all those near it. Now Celaeno is intrigued! Where is the real relic? Nopony knows for sure, but legend has it that somewhere in Equestria there is a map that leads the way. Calling upon her old friend Daring Do, Rainbow Dash leads the pirates on a treasure hunt like no other.

While Fluttershy and all her best friends are showing Tempest Shadow around Equestria, they get a message from Skystar, the princess of the seaponies. She’s super bored and wants her pony friends to come down for a visit! Fluttershy is excited to see more of Seaquestria, so she’s off to the ocean for a vacation with her friend! But when she gets under the water — and is turned back into a Seapony — she soon discovers that not everything is smooth sailing. If Fluttershy can’t help clear up the tension, there could be a real battle at the bottom of the sea!
