An enemy from (and mascot of) the rpg series Dragon Quest. http://en.wikipedia.org/wiki/Slime_%28Dragon_Quest%29
The model has 224 triangles, has some very basic animations, and a few extra skins included. The unit supports team colors, but doesn't use them. To add team colors, simply edit the SLIME.dds's alpha channel.
To give the unit sound you should add the bits of XML I've included into your mod's AudioDefines and Audio3DScripts XML files.
