I set up the last thing--a scavenger hunt. But not just any scavenger hunt, a hunt for riddle bombs set up by The Riddler. A week prior to the party, I dressed up as The Riddler and made a digital video of The Riddler setting up the rules of the hunt. I did the video using my new digital camera and my laptop which came with movie maker software. At the party, I alerted the new superheroes that The Riddler was on the loose. I then played this movie from the laptop right to our large-screen TV. The Riddler put 6 Riddle Bombs somewhere and 10 villains left clues (special cards). Each child had to find a specific card, of which there were 10 (10 kids, 10 cards). One side of the card had a picture of a Batman villian. Other side had part of a larger picture--a puzzle with a riddle written on it. Find all the cards, and they have all the puzzle pieces to make the riddle. Solve the riddle, and they find the Riddle Bombs. The riddle was "What do you eat that is on fire, but is covered with things that are cold?" The answer is a birthday cake (candles are the fire, but it is covered with "frost"ing and "ice"ing). The parents helped with solving the puzzle of course. To make the cards, I used a sheet of homemade business cards and printed the villains on one side and the riddle puzzle on the other. Then I just separated the cards. To give a hint for the answer for the riddle, I printed a watermark of a birthday cake behind the riddle text.  When the riddle was solved (which was pretty quick), the kids went up to the cake which had a superhero picture silk screened on it and the 6 Riddle Bombs (dunkin donuts munchkins with candles)--for my son's 6th birthday. Only my son's superbreath could stop the bombs and save the day.
