Challenge Level/XP: 9/1100 + 1/300 per head over 4.
Toad-Hydrae resemble giant toads with multiple heads, although the body is somewhat longer than that of a toad, and the mouths of a toad-hydra are filled with nasty, sharp teeth. These creatures have one attack per head. Each head can attack either by biting or by flicking out its long tongue in attempt to grab (and later swallow) prey. A toad-hydra will not usually attack with more than two of its tongues; if attacking with three tongues, all of the tongue attacks are made at -1, if with four tongues, all the attacks are at -2, etc. If, however, the toad-hydra hits with one of its tongues, the victim is immobilized and the hydra may begin trying to gulp it down in the next round. Gulping attempts are treated as attacks, but rather than dealing damage in hit points, success means the victim is swallowed whole and will die in 1d4+3 rounds. Immobilized opponents can attempt to break free (successful saving throw at -5).
