Shellmon

Shellmon is a Champion Level Sea Animal Digimon. He has a forest counterpart in MoriShellmon.

Shellmon can withdraw into his shell for protection. The top of the shell can spin when he emerges from the sand. "The Official Character Guide", written by A. Ryan Nerz, considers Shellmon to be "extremely tough for a Rookie Digimon".

Digimon Adventure
After the DigiDestined's encounter with Kuwagamon, a Shellmon appeared under the sands of a beach where strange phone booths were lined up. Tai and Agumon engaged Shellmon in battle up to where Agumon Digivolved to Greymon for the first time and knocked Shellmon far into the ocean. After escaping the Dark Masters, the DigiDestined ended up in the same location and encountered the same Shellmon in the water (this time, it had dialogue). Biyomon and Tentomon were able to send it retreating.

Gomamon tried to pacify it but did not work. He was freed from the Dark Ring by Digmon, but then Ebidramon appeared.

When Digimon began to appear in the Real World, he appeared once more with an Ebidramon and a Gesomon in Australia while they were chasing an Australian Digi-Destined named Derek and his Digimon Partner Crabmon. Ikkakumon, Crabmon and Armadillomon drove them away with thought of them in food. The 3 Digimon later appeared being herded with a Whamon and a Raremon after Zudomon, Submarimon and Coelamon defeated Scorpiomon and took down the Control Spire. They were all sent back to the Digital World after Scorpiomon's defeat.
