Melonpanna and Rollpanna separately befriend Marin, a mysterious white horse with a special connection to the sea. Marin reveals a treasured sunken ship to Rollpanna, but Baikinman witnesses the discovery and decides that a ghost ship would make the perfect weapon for one of his schemes.

With Dr. Hiyari's help, Baikinman creates a terrifying vessel and targets Rollpanna's divided heart, hoping to push her completely toward evil and turn her against Anpanman. Melonpanna's love for her sister and Marin's trust become crucial as Anpanman faces both the ghost ship and a friend being manipulated into an enemy.
