Lloid is a character featured in Animal Crossing: City Folk for the Wii, found in the City Plaza's Auction House. He is a standard looking Gyroid, similar to the one that was stationed in the front of your house in the original Animal Crossing. He is very polite and will explain to you the basics of the auction house and when you can bid and when you can place items up for sale.
