|Poisonous Potato Essence|
Poisonous Potato Essence is an item added in 8.0.4 which can be used to permanently stop the growth of prehistoric creatures. This is an irreversible effect: once used on a Dinosaur, it cannot be undone.
When fed to a prehistoric creature, it fills 20 points of hunger. It cannot be eaten by players.
Poisonous Potato Essence is crafted from one chicken essence surrounded by four poisonous potatoes.
