Pischumon are very small, plump, yellow rodent-like digimon. It bears a similar appearance to its evolved form pikamon, but varies in a number of ways. Pischumon have diamond shaped ears on the top of their head, with the edges being black and the interior yellow. Underneath their head is a black pattern, that somewhat resembles a collar. Their tails are completely black, and resemble a small lightning bolt, similar to its evolved forms which are larger. Pischumon also have round, pink sacs on their cheeks, used for storing electricity.
