Towelket: One More Time 4 - Ocean is a freeware story-heavy adventure/RPG made in RPG Maker 2000.

Towelket 4 is somewhat of an ironic Peter Pan + Little Mermaid while also being full of references to the previous games. For the first time in the series you have an overworld resembling older RPGs like Dragon Quest. It also has the biggest number of party members to choose from.

A boy was led by a fairy to a mysterious ocean world called Bariland and goes missing. His best friends Mocha and Paripariume set out to search for him. They are captured by pirates and Mocha nearly ends up drowning, but is saved by the beautiful mermaid Koucha. Years pass and the fish-hats plot to take over the world. Can Mocha and his friends find the boy and stop the bad guys?
