The Poisonous Potato is a rare drop when harvesting potato crops, with a small chance of being obtained in place of a regular potato. Consuming it can inflict the player with a short-term Poison status effect, causing damage over time. Despite its negative effects, it is sometimes kept by players as a novelty or used in various player-created challenges. It cannot be planted or cooked, and its primary use is as a risky food source.
