A slurk's back is crusted with thick, dry slime and dozens of nodules. As a standard action at will, a slurk can squirt a jet of this slime from one of these nodules as a ranged touch attack against any target within 30 feet. The slime quickly hardens to the texture of cold tar, entangling the foe. Anyone the slurk successfully bull rushes or overruns is automatically squirted with back slime. The hardened slime can be removed as a full-round action with a DC 15 Strength check. The slurk's back slime grants a creature riding it a +8 bonus on Ride checks made to stay in the saddle, but a -8 penalty on Ride checks to dismount.
