A warped fungus on a stick is a tool crafted from a fishing rod and a warped fungus, primarily used to control a saddled strider while riding it in the Nether. Holding the warped fungus on a stick causes the strider to move in the direction the player is facing, and right-clicking boosts the strider’s speed at the cost of the item’s durability. The tool loses durability with each boost and eventually breaks. It functions similarly to a carrot on a stick, but is exclusive to striders.
