Poisonous Potato

A poisonous potato is a food item very similar to a normal potato, except that it also poisons the player for a short time (same effect as a spider eye). The poisonous potato is a drop when harvesting potato plants (2% chance of dropping from fully grown plant). The poisonous potato cannot be planted or baked like a normal potato. After eating a poisonous potato, you will lose 2 hearts (hence the poison).

Trivia

 * The patches of green on the poisonous potato are similar to real life. Green patches on real potatoes ("sun scald") contain higher concentrations of solanine, a toxic glycoalkaloid which is found mainly in the stems, sprouts and flowers of a potato plant.
 * Strangely, a poisonous potato restores more hunger points than a regular potato.
