This Treehouse is basically an add-on to any lego house. This piece uses approx 120 pieces, not including the baseplate, plants, minifigures and accessories. It comes with 4 minifigures, 6 plants, a bike and an epic lawnmower. The bike is not built by bricks, it is only one piece. Because this piece is fairly big, I would not cast it as a mini-kit set. There is also no back on the treehouse roof, this enables you to put minifigures inside the treehouse and move them around. This set is minifigure-scaled, and any type of minifigure with a small head accessory can easily fit in the treehouse.
