Tremers are large, leech-like creatures . They are only a minor threat and are a nuisance at best. They appear to be huge leeches, varying in size between a foot long and the size of a man's torso. They are consistently coated in a slime and adhere themselves to walls, floors, and ceilings, leaving a trail of slime behind them in their wake. They come in two, negligible varieties, Blue Tremer and Red Tremer. Blues are a dark blue, almost black, and have a segmented, pointed appearance, whereas Reds are a solid, teardrop shaped creature with a dull red tinge. When killed, they release a splatter of gooey blood, supposedly from recent meals.
