The Halloween Wizard's House was seen in "In the House".Rigby knocked on the door of this house to get candy, but no one answered. He got mad and threw eggs at the house, causing The Halloween Wizard to come out and curse Rigby. The house is very large, likely a mansion, and is faded brown with some designs and windows. It is unknown what it looks like on the inside. It was also seen in the part when Mordecai came there to apologize to The Halloween Wizard.
