Right-click while holding this item to summon Fresh Pants of your choice.
(Special pants excluded)
Right-clicking a Philosopher's Cactus opens a menu that allows the user to select a standard color of Fresh Mystic Pants. Special pants, such as Dark Pants and Aqua Pants, cannot be obtained from the Philosopher's Cactus. Upon selection, a message appears in chat stating that "THE CACTUS HAS SPOKEN!" and the player will receive the selected color of pants. 64 Philosopher's Cacti can be stored in one inventory or ender chest slot, making them a very compact way to store Fresh Pants.
TriviaDespite not being stated in the item's description, Philosopher's Cacti are kept on death.
