From Monkey Island wiki
Ozzie's House is Ozzie Mandrill's residence on Lucre Island. In the game it is not made clear if it is the former Governor's residence, or another house which Ozzie has chosen to live in. From the outside it is a fabulous, though slightly creepy, mansion with a scary watchbird over the doorway and a fountain in the shape of a shark's mouth. A single flower grows in the grass outside. Ozzie managed to arrest Otis for picking some of his flowers.
Inside, the mansion is a repository of Australian artifacts, firearms, and stuffed animals. The walls are decorated with portraits of Ozzie and Australian landscapes. Ozzie likes it because it reminds him of home as he plots to seize control of the Caribbean.
