Kabuto (3.5e Monster)

Combat
 (Ex): With every bite, enough blood is drunk to deal 1 points of Con damage plus one per 2 HD above 4. This restores 5 HP to the Kabuto for every point of Con damage dealt.

 (Ex): If Kabuto takes a full defense action, its natural armor bonus improves by 4 points for three rounds. Multiple full defenses do not stack.

 (Ex): As a melee touch attack that does not provoke, Kabuto can leap into an adjacent occupied square and attach itself to a target. It may then deal automatic bite damage every round (starting on the next round) unless grappled and removed, or knocked out/killed.
