Champion Horse Riders Party
Girls can become champion horse riders in this game. Have a couple large horse plushies and set up a course. Each girl gets to pick a horse and name it, then choose the event they want!
You should be able to set up the one course into many different events: jumping, racing and cross country. When it's a girls turn, she will have to complete the course with her horse and discover true horsemanship.
Give out medals to everyone. When the party is over, take down the course and put the horses back in their stall. What a busy day for your riders!
