Lime

Limes are found with Lemons in Dry Dry Desert's oasis. They restore three FP and can be cooked by Tayce T. to make a Tasty Tonic.

In one of Koopa Koot's favors, he says that he has been dragging his shell recently and want a "tart pick-me-up", for which he thinks a Lime should do the trick. If Mario brings him a Lime, he will say "Mmmmm... Yow! What a sour lime! That'll put a spring in my step", and reward Mario with three Star Pieces.

Trivia

 * Limes are mentioned in Lumpy's diary in Paper Mario: The Thousand-Year Door, where he states that the last revision of his foodstuff during his Dry Dry Desert expedition consists of Lemons and Limes.
