Lokai

Grandma Lokai is an orphan keeper in the Earth Kingdom. She houses young children in a tower near Hiroku Canyon. She is known to treat her guests like princes and princesses, often dressing them up in crowns, tights and other formal attire.

History
Grandma Lokai found Toph, Momo and Appa after they were separated from the rest of Team Avatar while flying to Hiroku Canyon. Excited at the arrival of new guests, Grandma Lokai dresses the trio in royal attire and treats them like young children, referring to Toph as "granny's little princess". Not long after, Katara and Sokka arrive, having just escaped a band of Earth Kingdom thieves. Delighted, Grandma Lokai orders for more tights, robes and crowns to be fetched, in order to accomodate for the arrival of two more guests. Aang soon arrives, enraged, and proceeds to attack Onku, one of Grandma Lokai's helpers, not knowing that the eastablishment was an orphanage. Katara breaks up the fight after seeing a picture of Grandma Lokai with Onku and the thieves she and Sokka encountered earlier, realizing that Grandma Lokai is an orphan keeper. Grandma Lokai apologizes for the confusion, and offers a bowl of Beetle-Worm soup to the group.
