Seal Island is home to Seal, Shark, and their cheerful group of friends. Life on the island used to be full of joy, and everyone believed those peaceful days would last forever—until an unexpected visitor, an orca, arrived.

And what should be done about the orca afterward? A series of seemingly thrilling (or maybe not?) yet heartwarming stories is about to unfold on Seal Island—
