Blood Drain (Ex): A tumbling mound derives its needed moisture from blood. It deals 1d4 points of Constitution damage to a grappled creature in any round when it begins its turn grappling the victim. Once it has dealt 8 points of Constitution damage, it releases its grip and tumbles away, sated. If the victim dies before the tumbling mound has drained 8 points of Constitution, the tumbling mound releases its victim and goes in search of a new one. A tumbling mound does not need to deal thorn damage to utilize this ability.
Improved Grab (Ex): To use this ability, a tumbling mound must hit a creature of any size with its slam attack. It can then attempt to start a grapple as a free action without provoking attacks of opportunity. If it wins the grapple check, it establishes a hold and inflicts its thorn damage with each subsequent grapple attempt (no matter who initiates the grapple, including a third party coming to the aid of the tumbling mound's victim). It can also begin draining blood once it has grappled a victim.
Thorns (Ex): Any creature that strikes a tumbling mound with a natural weapon takes 2d4 points of piercing damage from sharp thorns that cover the mound's body.
Skills: *Tumbling mounds have a +8 racial bonus on Hide checks in dry undergrowth or dead vegetation.
A tumbling mound attacks by throwing itself at a target, then driving as many thorns as possible into the victim's flesh to latch on. It feeds by sucking the victim's blood through a hollow "feeder" thorn. Tumbling mounds have enough cunning to choose lightly armored foes over those wearing heavier armor.
