It is a Digimon Baby which surrounds its body with a vaporous smoke. The computer kernel (Digicore) that all Digimon have at the center of their bodies is bare in this unique Digimon, and in order to protect this Digicore, it conceals it within a lot of smoke. Because Mokumon's Digicore is bare, when burning the smoke shrouding its body is changed, and it is a Digimon of the ecosystem. It scatters Smoke from throughout its body all over, escaping in the instant the opponent has lost sight.

It is a Digimon Baby which always surrounds its body with a vaporous smoke. Digimon are said to have a computer kernel, or Digicore, at the center of their bodies, but it is unique in that its own is bare, and in order to protect this Digicore, it conceals it within a lot of smoke. This smoke sometimes burns the Digicore due to an outbreak, but this doesn't seem to harm Mokumon or others. Also, because it is still evolving, when it encounters an opponent it immediately runs away. Then, it scatters Smoke from throughout its body all over, escaping in the instant the opponent has lost sight. As stated earlier, because it isn't particularly harmful, if you happen to see one it would be best to be quiet.
