Inside the penguin house at Uenohara Zoo, the penguins entertained visitors with their cute movements. Then, an announcement is made that the park is closing, and all the penguins who had been performing until a moment ago begin to go home. Ginpe, who came to the zoo as a mid-career hire, suggests to the penguins that they rehearse every day to better entertain the guests. However, the penguins don't want to work outside of regular business hours and go home.

This is the comedic story of their everyday life!
