LEGO Creator Treehouse 31010 Toy Interlocking Building Sets. Create your very own treetop hideaway with the 3-in-1 LEGO Creator Tree house. Open the secret trapdoor and climb up the fold-down ladder. Use the gray bucket to lift supplies up with the winch. Fill the red bucket with water and tow it up to keep unwanted guests away. This detailed playhouse includes a yellow wagon for transporting all your favorite things to your treetop hideaway, a hollow tree for storing your secret treasure map and a dog. Remove the roof for easy access to the storage area and sleeping bag, or detach the entire Tree house. Rebuild into a cute lakeside hut with a jetty and pizza oven or a 2-story farmyard barn with a garden and wheelbarrow using the supplied alternate building instructions. Includes a child minifigure.
