We did a Kim Possible/Mission Impossible Party for my 6 year old daughter. For the invitations, we had my 9 year old son record a message with Kim Possible music playing faintly in the back, Your Mission, should you choose to accept it is... and ended with a destruction countdown. I made a cover for the CD case out of a Kraft Brown colored cardstock and added "confidential" in red with a rectangle around it. It was then placed in a manilla envelope for delivery and left on the doorsteps of all girls invited to the party. On the day of the party, the girls arrived to the door, which read: Taylor's Interpol Agency. We had Wanted Posters of the Kim Possible Villains on our "Wall of Most Wanted" I had pictures of KP in the frames of our pictures in the house. My daughter was dressed as KP. We had the girls working on a craft in the kitchen when the doorbell rang. Of course, they all got up and ran to the door. No one was there, except a Ransom note. "Cuppy Cake" was being held for ransom and they had to find her before it was too late. There were missing photos of Cuppy Cake on the walls throuought the house. The Ransome note had a rhyming clue as to where to find the next clue. We had about 5 clues around the house, in the pocket of one of the coats in our coat closet, on my daughter's art easel and so on. The girls were so excited looking for these clues, it was adorable. They were all crowded around reading the notes. We would have to assist slightly to help them think through what the clues meant, but they got them pretty easily. Cuppy was finally found in the treasure chest hiding in the corner of our family room. I had gotten some KP toys to give as thank you gifts, which I wrapped in brown paper and my husband hid out in the backyard. We then had clues written backwards and in 3-D. They had KP 3-D glasses they had to use to read the message in the mirror to find out where their each individual gift was hidden. Once they found them, they all sat in a circle and opened them at the same time, since they were the same gift, so they could all see what they were searching for at the same time.  I made a KP Cake and we had cake and opened gifts. My daughter thought that was the best birthday ever!
