The cake pan was a little more difficult as the Cookie Monster pan isn't made anymore. I was able to find one on eBay. Actually, I found two on eBay. The large Cookie Monster and the small Cookie Monster that we used for the smash cake.
I then used glue to add the googly eyes to the party hats and cups.
And had them set up on the table with the food.
Since it was mostly adults at the party, a lot of the hats weren't worn, but the boy had a blast!
