With Grandpa out of town, Kukuru and Fuuka work together to feed and weigh the penguins. Kukuru notices something wrong with one of the penguins, and decides to call the vet, who is on maternity leave.

Kukuru is tasked with coming up with ideas for an event, but her proposal comes with some serious challenges.

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.

The director announces a new research facility to be built at Tingarla. Two people will be chosen to study at a similar facility in Hawaii.
