The Haunted House is an amazing set. It is both fun and challenging to build. The fun part of displaying and playing with the Haunted House is not necessarily in its functionality (although it was a great idea to make it open on hinges), but is in its details. My daughter and I both love Halloween and the Haunted House is the perfect center piece for the Monster Fighters theme. To add a little functionality, we modified the top spire by making the top of it rotate. For anyone so interested, here's the pieces we used: 1. One 2X2 turntable plate (which includes the 2X2 square base and round 2X2 spinner which snaps into the base). 2. One black 4X4 plate. 3. Two black 1X2 flat plates. 4. Two black 1X4 flat plates. 5. One medium grey sign post with a 2X2 base. 6. One black 1X1 conical-shaped round brick. Build the spire exactly as directed by the instructions, except do not add the hand rails and round corner elements to the top of the spire. Instead, install these onto the black 4X4 plate which will serve as the top piece of the spire. In the center of black 4X4 plate, connect the sign post with the 2X2 base and add the black 1X1 conical-shaped round brick to the top of the sign post, this will serve as your spinner mechanism. On top of the spire, place the 2X2 turntable plate in the center of the top of the spire, then add the two 1X2 and 1X4 black plates around the edges of the turntable (this fills in the gaps so that it looks like one solid piece). Now attach your black 4X4 plate with hand rails, round corner pieces, and spinner to the turntable. You now have a spinning spire top that you can attach your ghosts and other flying monsters to and spin them around like they are flying around the spire of the house (particularly fun to do at night when the ghosts are glowing). As you can see from the pictures, we also made our own Headless Horseman. Another challenge for the brave Monster Fighters to tackle!
