Fuka finds out why Kukuru is working so hard to keep the aquarium running. She’s asked to feed the penguins for an event, but things don’t go quite as planned.

It’s Gama Gama Aquarium’s last day, and it’s receiving a lot of visitors. The staff are hard at work to make it memorable.

A year has passed since Gama Gama closed, and Kukuru has found work at Aquarium Tingarla. But for some reason, she’s assigned to Marketing.

A penguin egg is about to hatch at Tingarla. The penguins team is set to stay the night at the aquarium, but Chiyu can’t make it, so Kukuru offers to take her place.

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.

With work not going smoothly and having seen Gama Gama demolished, Kukuru leaves work to go to the sub-islands.

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