Mandark's House is the house where Mandark, Lalavava, Oceanbird, and Windbear live. It is overly hippie like because of how Oceanbird and Windbear choose to decorate it.
Mandark's House is a small yellow adobe with a brown roof and two floors. On the inside it is completely yellow as well.
In seasons 3 and 4, the house is white with a green roof, and its interior is wooden with no wallpaper or painting, with candles and colorful peace sign posters all around.
Behind the house is Mandark's Laboratory which is exceedingly larger than the house and can be seen from afar.
