Venodiente is a glowing, mutated crocodile in Valle De Oro that escaped a crocodile reserve after exposure to a chemical dump. It shrugs off bullets but burns well, and its leather trades for unique gear.
Venodiente has killed dozens of reserve workers and Animal Services staff, according to notes you find. It is aggressive, poisonous and lurks in the swamp water, where its glow gives it away.
Bring fire: incendiary rounds, molotovs or a flamethrower. Normal bullets do little. Fight from dry ground, and gear with poison protection helps against its attacks.
