One day the owner of the store tries to sell him an old Medabot, then one day a kid from the screws has his Medabot stolen and his leader goes to see the punks who stole his friend's Medabot and they start picking on Ikki's friend, so Ikki runs and finds a medal in the river and he buys the Medabot and saves his friend. his name is Metabee.

Spyke and Cyandog never seem to win a Ro-Battle so Samantha kicks him them out of the Screws gang. Spyke and Cyandog ask Metabee and Ikki for training help and they find out that Cyandog is terrible at battle because he has the wrong type of medal.

Penguins are cute with their black and white bodies and small wings, and the unique way they waddle when they walk. When they stare at you with those beady eyes, it just takes your breath away! Along with a little boy named Paco and his Medabot Pingen, Ikki and his friends break into a strange animal park operated by the Rubberobo Gang to help send hundreds of penguins back to their home in Antarctica. Pingen, a Penguin Type Medabot that is not suited for battle because of its weak armor, was a present from Paco's dad in Antarctica to keep Paco company while he is away. Rubberobo's plan was to build a zoo to raise funds for taking over the world! The mistake was trying to make a zoo with only penguins. Their bizarre plans were spoiled when Pingen, Paco and his new friends succeed in setting the penguins free. Ikki and the others are happy to help send the penguins home to Antarctica, but hate to say goodbye to Pingen.
