For my daughter's 4th birthday she wanted a Scooby Doo Mystery Party.We had a lot of fun planning the party. We rented a castle moon bounce for the children to play in at the beginning of the party. It was an outdoor party so the gifts were left on a special gift table. While the guests were jumping, my husband put the gifts in the trunk of his car. When we went to open the gifts, they were gone. All that was left was a long piece of gauze on the table.  The guest we told that they had to solve the mystery of the missing presents. I told the guest that we would go ahead and do the rest of the party games and maybe we could find more clues as to where the gifts were.  Next we did the pinata and when it bust, along with the candy, there was a scooby doo key chain for each guest and a long piece of gauze as well. The last game was musical chairs.  The winner won a bigger toy car and everyone else won a match box car and each had gauze wrapped around it. At this time I told the guests to think about the clues. The guest then decided that the gifts were inside of the car in the driveway. As we were making our way to the car to look inside, my 12 year old son ran out dressed as a mummy, not a scary mummy. All of the guest chased him. Then my daugther caught him and unmasked the fake ghost. For goody bags I gave out tupperware dog bowls with grahm cracker scooby doo dog bones and gummy scooby doo snacks.
