This was the picture I found online. It looked like they might have used paper and maybe plaster of paris. It was hard to tell but I think the spray foam had to be easier.

First, I used a marker to draw the image of the monster of the board. It was rough drawing, something to use as a guideline to spray the foam. I used the wiggle eyes to trace the area I needed to leave open for the eyes. I also traced two circle where the nostrils would be. I used the disposable cups as a guide to trace the circles.

Next, I cut out the two circles for nostrils. I used a hole saw. See shopping list for the item. I then sanded the holes to avoid wood splinters.

I read that the spray foam will stick to the wood better if it was slightly damp. I wiped the wood with a wet towel. The wood was not soaked, just slightly damp on the surface.

The next day, I took a serrated knife and started to shape the foam. It doesn’t have to be completely smooth. In fact I found that the pits make it a little more gross.

I cut around the area where the wiggle eyes would be glued. Make sure that the eye will lay in the space. I cut out the cups that were hold the nostrils open.

Once shaped, you can now start painting the monster. Be warned, the wood and the foam will soak up quite a bit of paint. I used at least 16oz of green paint. Paint the entire monster in the main color, then you can start adding darker and lighter colors on top to give it dimensions.

I added some text and a few “booger” images to add to the overall look.

The day of the event, the kids would reach into the nostrils and either get candy or they would stick their hand into slime (boogers). The look on kids faces when they reached into slime was priceless. 😂
