Mint Leaf

The Mint Leaf, known as the Sweet Potato (さつまいも) in Japanese versions, is an item that appears in Kirby's Dream Land. If Kirby eats one, his aerial game becomes better, and he can spit an unlimited amount of air bullets much faster and farther for a limited time. Originally, it was supposed to increase Kirby's "burping", as a sweet potato can. When it was localized as a mint leaf, it gave Kirby "minty fresh breath", as it said in the Super Game Boy guide.

When Kirby fights Kabula, he obtains a special Mint Leaf that lasts until the battle is over. When it is obtained anywhere else, it only lasts for a short time.

In Kirby: Right Back at Ya!, episode 73 Dedede's Raw Deal, the sweet potato does appear. King Dedede uses this on a potato sushi to give Kirby the hiccups making it hard for him to battle a monster version of Squishy. It wasn't changed into a mint leaf in the English version however.

In Kirby: Triple Deluxe, it appears in the Kirby Fighters sub-game. It has the same effects as its previous appearances. Kirby will automatically begin spitting air puffs once the item's obtained, pausing briefly after every few puffs. When the Mint Leaf is used up, Kirby will expell a giant air puff.

Trivia

 * In Kirby: Triple Deluxe, the Mint Leaf has the appearance of a sweet potato in Japanese versions, and a mint leaf in other versions.
