Jubokko, also known as vampire trees, are sentient evil plant monsters.  They are immobile (but see below), but have several means of luring victims to them.  Once a human, demi-human or humanoid is under their branches, they strike one or two targets, entangling the victims with branches if their attacks succeed.  Entangled victims are drained of 3d8 hit points each round.  Each round after the first, victims may make a saving throw vs. dragon breath to escape before they are drained again.  Jubokko can use the following spells: growth of plants 3/day, hallucinatory terrain 3/day, dimension door 3/day.  They may also control plants, as the ring, at will.
