Playing with words, silly rhymes and sounds are a favorite activity for children and can be a blast at parties. See who can say these quickly three times:
Which witch wants Winnie's watch?
Good ghosts go galloping gratefully.
Slow snakes slither, speedy spiders spin.

The key to success for any party is to plan ahead, organize yourself, anticipate everything, and then realize that you can't anticipate everything. Remember that if you're relaxed and having fun, your guests are more likely to have fun. Dress up and get into it. Enjoy. It'll be a real treat!
