The snallygaster is an ambush predator, attacking its prey from above. Once it spots a potential victim, it dives toward its unsuspecting foe, using the fall to build up momentum. Once its foe lies dead or unconscious, the snallygaster uses its tonguelike tentacles to slurp up the victim's blood. The only thing a snallygaster craves more than blood is alcohol, and it spends much of each autumn scouring its territory for fermenting fruit, on which it gorges itself until thoroughly inebriated. Intoxicated snallygasters are extremely aggressive.
