My Little Pony: Set Your Sail #2

Pipp was totally salty about being sent to the seven seas for princess duties, so when Zipp receives an oddly chipper message from her sister, Zipp is more suspicious than a clownfish in a clamshell. She takes matters into her own hooves-er, fins and travels to the Sparkling Sea where she meets Princess Anemone. The sea princess' odd behavior and Pipp's absence make Zipp wonder if she can trust the seaponies and if their sparkles are only scale-deep.
