The Whiskered Eggplant is a power-up in Mario Superstar Baseball exclusive to Waluigi. In Challenge Mode, Waluigi had to purchase this eggplant item before he could use the Liar Ball, which is his Power Shot. However, Waluigi can only buy this if Wario is his team captain, or if he is on another captain's team. Also, this item is only available in Challenge Mode, as Waluigi is able to use the Liar Ball in Exhibition Mode without the need of an item. The Whiskered Eggplant is, as its name indicates, a purple eggplant with a moustache.
