Aquarium Tingarla is visited by a TV crew who is there to document a penguin hatchling’s growth. Fuuka wants to turn down her opportunity to be on TV again.

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.

Aquarium Tingarla is hard at work preparing to carry out the aquarium wedding project that Kukuru spearheaded.
