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