Giant gar live in deep rivers and lakes. They can swallow prey whole on an attack roll of 20, including creatures up to Man-sized. A swallowed person has a cumulative 5% chance per segment of drowning, but if he or she has a cutting weapon, may cut him- or herself free. To do so, 25% of the giant gar’s total hp must be inflicted. Any piercing attack against a giant gar has a 20% chance of causing equal damage to a swallowed creature.
