Medabots (1999) : 1x19

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.
