Lokai

Grandma Lokai was an orphans' caretaker in the Earth Kingdom. She housed young children in a tower near Hiroku Canyon. She was 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 dressed the trio in royal attire and treated them like young children, referring to Toph as "granny's little princess". Not long after, Katara and Sokka arrived, having just escaped a band of Earth Kingdom thieves. Delighted, Grandma Lokai ordered for more tights, robes and crowns to be fetched, in order to accommodate for the arrival of two more guests. Aang soon arrived, enraged, and proceeded to attack Onku, one of Grandma Lokai's helpers, not knowing that the eastablishment was an orphanage. Katara broke 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 offered a bowl of Beetle-Worm soup to the group.
