The pirate island - the perfect place hide your treasure.
This is a mud hut with a skeleton standing guard to make sure no one steals the treasure. There is a treasure map inside and a bed in case a weary pirate needs to rest their tired legs after a day's rampaging!
I built this as it was clearly an important need - nothing like this existing for battle-tired pirates to have a rest in the middle of a campaign of pillaging in the lego universe.
It would make a great lego set as it has lots of detail and can fit into a wide range of other existing lego sets.
