Lychee nut



Leechi nuts are a type of fruit native to the World of Avatar. They are reddish-brown in color, and are known for their abundance and taste. Their fruit, or possibly their leaves, can be used to make tea, as they were mentioned by Zuko whilst he was working at the Jasmine Dragon in Ba Sing Se. They also are the source of leechi juice. Leechi nuts are known to grow in the Earth Kingdom, and are suspected to grow in the air temples, as Momo demonstrated a great liking for them. These nuts were often used as bait for traps to catch small animals.

Connection
Leechi nuts are also a fruit in the real world, more commonly known by their proper name, "lychee", and native to southern China. They are nuts only in name, as they have a blunt, spiky rind covering the outside, making them more similar to a berry of some kind. It contains inedible seeds separated by white, delicate grape-like pulp. It is unclear whether or not leechi nuts in the world of Avatar are in fact nuts, or berries like their real-world counterparts.
