Sandy's Treedome (The Life of SpongeBob SquarePants)

The Treedome is the residence of squirrel Sandy Cheeks, located in Bikini Bottom. It gains its name from the glass dome that surrounds it, allowing Sandy to survive underwater.

Design and features
The Treedome is most notable for its powerful, airtight polyurethane dome that envelops it, protecting everything inside from water and allowing Sandy to survive underwater without her special pressurized suit. The whole ground inside the dome is covered by grass, with flowers few and far between. In the center is a large oak tree which provides Sandy with oxygen and acorns for her to eat. The tree also contains Sandy's living quarters.

Sandy's living quarters contain a wooden bed, a rocking chair, and nightstands, all made out of sticks from the tree. There is a sizable living room with rugs, an LCD television, and a sofa.
