Komugi and Iroha are invited by their dog trainer friend Inuzuka to try a dog sport called Agility. At first, Komugi doesn’t understand the obstacle course and just runs through everything.

For their summer independent research project, Komugi and the others go to the beach in Animal Town. They decide to play in the ocean until the sea turtles begin to lay their eggs, when a Garugaru appears.
