The touch pool, where people are invited to touch sea creatures with their own hands, is the biggest event of the summer at Gama Gama Aquarium. Kukuru, Kai, Kuuya and Fuuka are hard at work to prepare.

Kukuru and the crew brainstorm for ways to attract more visitors to Gama Gama Aquarium. They decide to try selling some sweets.

Haebaru Chiyu is at Gama Gama Aquarium from Aquarium Tingarla to study how they do things, but she butts heads with Kukuru.
