A hairy Rare Animal Digimon completely covered in white fur. It lives in the hinterland of snowy mountains, and it is very unlikely to come across one. There are many reported sightings of Mojyamon, but no evidence to prove its existence, so for a long period it was considered to be a Digimon based on myths. With its carefree personality, it is never belligerent. However, it considers its den and territory to be sacred ground, and it will never permit this sacred ground to be invaded. Its Special Moves are a huge icicle made by causing the moisture in the atmosphere to instantly freeze (Icicle Rod), and throwing the bone of an Ancient Digimon which had become fixed in the ice (Hone Hone Boomerang).

全身を白い体毛に覆われた毛むくじゃらの珍獣型デジモン。雪山の奥地に生息しており、なかなか出会うことができない。モジャモンの発見例は数多く報告されていたが、その存在を決定付ける証拠が無く、長いあいだ空想上のデジモンとされていた。のんびりやの性格で決して好戦的では無い。しかし、自分の住処や縄張りは聖地と考えており、この聖地を荒らすものは決して許さない。必殺技は大気中の水分を瞬時に凍らせて造る巨大な氷柱『アイスクルロッド』と氷づけになっていた古代デジモンの骨を投げつける『骨骨ブーメラン』。
