cool, i like Great Fortitude although Multiattack is perfectly fine. 
borrowing from the iron golem a bit for the breath weapon format:
Breath Weapon (Ex): 10-foot cube, cloud of foul fumes lasting 1 round, free action once every four hours. Creatures inside the cloud must succeed on a DC 13 Fortitude save or be nauseated for 2d6 rounds. The save DC is Constitution-based.
how are these two abilities:
Disease and Poison Resistance (Ex): As a carrion eater, the DRAGONET needs to be highly resistant to toxins and disease-causing microbes, which often build up as a result of decay in rotting matter. They receive a +6 bonus on Fortitude saving throws against poison and disease.
Voice of the Dead (Su): A DRAGONET is possessed with the memories and voice (but not the intelligence or other mental qualities) of any intelligent being whose marrow it consumes. This functions essentially like a speak with dead spell, but with a duration of 2d4 hours. A complete corpse is not needed, since the dragon's mouth voices the answers from the spirit of the departed.
