Keroppi was born on July 10th. He lives with his brother, sister and parents in a big house on the edge of Donut Pond, the largest and bluest pond around. Most of his best friends live nearby, including his girlfriend, Keroleen. He is the natural leader of his large group of friends, and he leaps to help his pals in their time of need. Keroppi and his friends share his love for playing games, especially baseball and boomerangs. But most often he is seen with his little snail friend, Den Den, always tagging along and usually a little behind.
