The swamp has an outhouse. And the path to Shrek's Garden, where he likes to grow weeds. In the Third Shrek film, Shrek builds a mud water slide for his newborn babies. There is also a mud shower, and a large courtyard-like area where the fairy tale creatures were taken in the first film. It also Shrek's hut where Shrek lives alone in the first film. After he gets married at the end, his wife moves in and then later their three children are born and live there as well. In the alternate reality, it is an empty tree stump with no doors or windows carved into it and the trees have rotted away and weeds cover the courtyard and Shrek's Garden is gone. Shrek originally did not own the swamp, it was part of the lordship of Duloc and the lord of Duloc used the swamp is a dumping ground for the Fairy tale creatures after he forced them to leave their homes in Duloc, disturbing Shrek's solitary existence. This becomes Shrek's main motivation to rescue Fiona so Farquaad would give him the deed and clear out the Fairy tale creatures.
The Swamp House contains two rooms. As you enter you'll come across the main room, which functions as both a kitchen and dining room. There is also a bed for the Ogre Triplets. And the west of the main room is Shrek and Fiona's bedroom. In Rumpelstiltskin’s universe there is no furniture in the house because it is just an empty tree stump with no doors of windows carved into it. Outside, he has an ogre mud bath where he can relax and play with his children.
