Chuumon

Chuumon is a Rookie Level Animal Digimon. His name comes from the Japanese word, chuuchuu, which is the sound that mice make in Japan.

Chuumon looks like a mouse. They are often found in the company of a Sukamon. Chuumons and Sukamons strong friendship came when Chuumon was being chased and fell into a trap set by a network cannibal and Sukamon just happened to be there when Chuumon tried to escape.
