Triple the number of pieces as in the original 3-in-1 set, so you can have all 3 models built at the same time! I believe this set is discontinued. In great used condition. Light gray 2x2 plates with socket are substituted for black 2x2 plates with socket. Smooth 1x2 green bricks substituted for textured green 1x2 bricks. Building instructions are available on Lego's website. Comes to you fully assembled and packaged with care, though some pieces may come apart during shipping.
