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

A dolphin is lost in the waters near Tingarla. Kukuru is eager to check up on it, but she is busy preparing for an upcoming project proposal, so the staff take turns visiting the dolphin.

Having watched the sea turtle hatchlings, Kukuru returns to Tingarla with a renewed sense of purpose, and resumes work on the wedding venue project.
