Ideas for a parade we want our daughter in?

Where we're from we have a festival with a parade and carnival. This year the theme is STONE AGE STRAWBERRYS. So my idea was kinda similar to THE FLINSTONES. I was going to decorate a barbie jeep she has like the flinstones car and dress her up kinda like pebbles but with a red with black polka dots. I was also thinking of taking an actual chicken bone spray painting it red and putting black dots on it and putting it in her hair. or do you think it's gross. I really need to know what you think of this idea or if you have any other ideas. Im not sure how im going to do the car. Any ideas very appreciated and welcomes. THANKS
