You'll need

Directions

  1. Stitch the dollar store plastic tablecloths together with a zigzag pattern to form the massive Stay Puft head.
  2. Use a small household fan to blow air into the head, inflating it to full size.
  3. Secure the structure with tie-downs and weigh down dollar store bags filled with rocks to keep it stable.
  4. Build a ramp from lightweight foam to ensure the head sits level on the roof surface.
  5. Apply acrylic paint to the face, then seal it with a spray lacquer coat to protect against moisture.
  6. Assemble a Snoopy-style doghouse by gluing pieces of pink insulation foam together.
  7. Run a soldering iron over the foam to burn in lines that mimic wooden planks.
  8. Blend two shades of wood grain paint onto the roof using a chip brush for a realistic finish.
  9. Draw and cut out the outline of a Terror Dog head from pink foam with a utility blade.
  10. Sand the edges of the Terror Dog head to smooth and round them.
  11. Place a clear plastic sheet over the eye sockets and glue red dollar store lights behind them.
  12. Paint the Terror Dog head black, then add lighter gray highlights to create depth.
  13. Finish the look by adding a plastic dollar store chain and a black velvet curtain.
  14. Direct fog from a fog machine into the doghouse doorway for a spooky atmosphere.
  15. Mount a proton pack on an adjustable stand and use a steel bar to secure the wand for photos.
  16. Make a proton stream by wrapping a red plastic tablecloth around white LED rope lighting and taping blue EL wire along the length.
  17. Drill holes in an aluminum bowl to transform it into a vintage-style colander for headgear.
