We went to a great party at a friend's house last year.
1. She had small rocks painted white or orange on a table and black permenant markers. The kids got to decorate a ghost or a pumpkin rock.
2.Each kid was given a white lunch bag to decorate. Each bag had numbers on it (1-7, I think). Once the bag was decorated, the kids went to different stations to get a treat (such as a piecoe of candy or a small toy) Each station marked off their station number on the bag so the kids could only get 1 thing from each station. Sometimes they had to play a game at the station to get the treat.
3. They had a costume parade.
4. Pinata.
5. Follow the map to find the treasure.
6. Fill empty water bottles with rice. Add small items like googly eyes, a safety pin, a pom pom, letters, felt pirate pieces, sequins, a bell, or other small things. Put the top on and seal. Shake up the bottle. Thd kids have to turn the bottle to find the items inside. Make a pre-printed list of the itmes to find and attach to the bottle. Each kid makes their own bottle. Use funnels to pour the rice. The kids had a blast!
