Merman in my Tub Vol. 3

The ill-fated Tatsumi, who used to live alone, is now the unwitting host to a growing menagerie of undersea creatures. His bathtub has become the abode of the self-indulgent merman, Wakasa, with regular visits from his aquatic friends--the octopus Takasu, the shellfish Maki, the jellyfish Mikuni, the shark Agari, and the newest member, the starfish Goromaru. With the New Year upon them, it's time for sweets, bean-tossing and more, but can a tub this small possibly hold a crowd this large?
