The Rabbit Gods are rabbits that reside on the moon, thus earning them the nickname "Moon Bunnies".
They come down to Earth every once and a while to sell rice cakes in their shop. The shop is said to be the location of the elixir of life, which is impossible to find anywhere else. Their shop only opens for fifteen days. As a result, they don't sell many rice cakes, and don't earn much money.
The current Red Elder Jeokyeon comes to the human world hoping to obtain the elixir, but is forced to wait for the arrival of the moon rabbits.
