Apple

Apples are recurring items found in, and.

A Link to the Past
In, Apples are a health-restoring item that can only be obtained by dashing into Trees with the Pegasus Boots. Apples are also the answer to one of the Lumberjack's riddles in A Link to the Past & Four Swords.

Twilight Princess
In, Apples are found in the stalls of Hyrule Castle Town's South Road. However, Link cannot actually take or use them.

A Link Between Worlds
In, Apples serve the same purpose as in A Link to the Past, recovering one Heart. This time around they can be stored in Bottles. Next to Link's House, an Apple tree grows Apples with every StreetPass encounter, starting with three and reaching a maximun of 20.

A Link Between Worlds also introduces Green Apples, restorring three Hearts instead; considered by the StreetPass challenges as an upgrade of the standard Apples. Green Apples grow randomly on the same trees as standar Apples, most commonly on the Apple tree near Link's House.
