Poketto monsutâ Bonnie for the Defense! (1997– ) Online
While Satoshi and Serena do some special training and Citron works on his inventions, Eureka explores the forest, where she meets a trio of kids who call themselves the Laplace Defense Force. They show Eureka to their hideout and introduce her to their friend Laplace, who is recovering from an injury and seems to be running a fever. The three of them really don't trust grown-ups, but when Satoshi , Serena, and Citron come looking for Eureka, the kids reluctantly agree to let Nurse Joi make a house call to their hideout. After some medical attention, Laplace is feeling much better, but it keeps looking out toward the water and crying. Citron figures out that it misses its ocean home, and the kids decide to take it back there. Despite a boulder blocking the way and a run-in with the Rocket-Dan, Laplace is soon reunited with its family. Eureka bids farewell to her new friends, and our heroes resume their trek to Hiyoku City.
