We hope you take this offer. Write the date, the place, and when it will be held. For decorations you can draw pictures of the mystery machine and put up mysterious looking pictures like the ones they have in the scooby doo shows. Now the point of this party is they have to find the mystery bags. Take a plane box and decorate it like a treasure chest, use glitter, markers, glue, construction paper, and more to make it look like a treasure chest. Then hide it some where and fill it with the mystery bags, in the mystery bags, put things like candy, little prizes and toys, like glowsticks, silly putty, keychains and things like that. You can either buy plane old bags anduse those, or you can decorate a paper bag and write, Mystery Bags and then decorate it. The next thing you should do is make clues for you're guests and hide them in the rooms you plan to have you're guests solve the mysteries in. Like finger prints, notes, feathers and thigns that have to do with the Mystery Bags in the treasure chest. Next decide what kind of food to have, you can have things that Scooby and Shaggy Like, like malts and shakes, burgers, fries, chips and more. Then decorate you're kitchen like a diner type place since that's wear Shaggy and Scooby always go. Find stools, for the counters. Put those plastic covers over a plate of donuts. Put coffee cups and coffee pitchers on the tables. Things like that. Have you're guests choose whatever they want, act like a waitress and write it down on a little notepad. For desert have ice cream in tall glasses or ice cream shakes, and have slices of cake for each guest. To go along with the mystery have a family member or friend dress up as a scary monster or a villan as one of the obstacle courses for the kids along the way. When the kids find the mystery cases, they have solved the mystery! Give them there mystery bags, then you can also give them a certificate for solving the mystery.
