Numemon

Numemon is a Mollusk Digimon whose name and design are derived from the onomatopoeia for slimy (滑々). It possesses a slug-like body. It prefers dark, gloomy environments, and has neither offensive power nor intelligence. A Digimon becomes a Numemon if mistakes are made in raising it, but as a matter of fact, there appears to be some hidden secret...

Digimon Adventure
The DigiDestined encountered the Numemon in the sewers after making it out of the factory that Andromon was in. Some were seen in fake vending machines where one of them tried to get a date with Mimi and got angry when she turned him down. The Numemon chased them, leading each of the DigiDestined into Monzaemon which scared the Numemon away. Monzaemon captured all the DigiDestined except Mimi and Palmon. The Numemon later appeared to protect Mimi from Monzaemon before Palmon Digivolved to Togemon and beat the Black Gear out of him. Later on, a bunch of Numemon worked on a ship run by Kokatorimon, a servant of Etemon; the Numemon fled when Togemon knocked Kokatorimon into the ship's smoke stack. A bunch of Numemon were customers at Vegiemon and Digitamamon's diner and some were being trained by Nanimon for Myotismon's army.

Digimon World 3
Numemon are encountered several times throughout the game, alternating in color. For instance, formidable Numemon are found within both of the Jungle Shrines, with the same action: He will flee after some turns. Those Numemon can be a good key for leveling up your digimon, because they're easy to defeat (it's advisable that your digimon have mega digivolution and/or level between 40-50) and they drop a lot of EXP (AS:around 250 AM:around 290). The strongest are in the South Badland of Amaterasu Server. There is also the BlackKingNumemon found in Amaterasu's Sewers of the Dum Dum factory, along with the Numemon disguise that Lucky Mouse wears to hide himself.

The different types of Numemon have different powers:

Purple (AS Jungle shrine): His attack doesn't do much damage, however he will decrease your digimon's defense. He will flee after 2 or 3 turns.

White (AS Ice dungeon): Ice properties

Fire (AS Fire Dungeon): Fire properties

Brown (AM Jungle Shrine): His attack is normal, but stronger. He will flee after 2 or 3 turns too.

Pale: (AM South Badlands and North Badlands East) He is stronger than others. It is the digimon who gives more EXP throught the game (Excluding Bosses, Leaders & Tamers). In the PAL version of the game, white, green, blue and brown Numemon can be found in Amaterasu's Circuit Boards undergound once Galacticmon has been beat. It is also available as a Brown Champion Card with 10/7.
