Richard's Villa
Richard's Villa is an area on Koholint Island, just south of the Pothole Field, where Richard lives in Link's Awakening. Richard's Villa contains four frogs, which is a reference to the game he originated from, the Japan-only Kaeru no Tame ni Kane wa Naru ("kaeru" is the Japanese word for "frog"). It also contains a basement which leads to the Pothole Field.
Trivia
If Link wait in Richard's house and let the tune play long enough, it will eventually break into a familiar tune hidden in several other Nintendo Games (examples being Mario Paint, and Animal Crossing, in which the song is known as K.K. Song). This is unofficially known as "Totaka's Song" and is a hidden melody that Kazumi Totaka would place in games that he worked on.
