Mudge

A Mudge is a 5-7 hand-long lizard with slimy pustules all over its body. Most at home in swampy terrain, the Mudge has webbed feet that enable it to move quite swiftly even in sandy terrain. The Mudge has an unquenchable thirst and energetically seeks out new liquid sources. Since a Monster's body is actually composed of 77% water (or is it 93% fat?), the Mudge will home in and clamp its teeth on you. It extends a tongue-like sucker into a wound to eventually drain all the liquid from the victim's body. Finish it off with a nasty Pointed weapon.
