Sarah, who's home-schooled, spent a little over 6 weeks making the film.
"I took over about 1700 photos just moving each thing a tiny wee bit, then taking another photo," says Miss Ridsdale.
The movie involved the whole family with her parents helping with voice overs of the characters.
"Janet and I are incredibly proud of Sarah. She has got this special ability to understand the environment and what's going on and what's important and can put that into a movie, and you know she's enjoyed the claymation and the creativity and to deliver a really good message," says Mr Ridsdale.
With talent like hers, it's likely New Zealand hasn't seen the last of Sarah Ridsdale.
