When Burnination has forsaken the countryside

I'm confused. Every single time that I play Peasant' Quest I always end up five points shy of the full 150 points possible. I've heard that if the baby is thrown into the lake it returns with a soda for five points. Every time that I try to throw the baby in to get the soda I am unable to do so. If you are able to confirm this for me I'd be extremly grateful. Let me know if this rumor of the five points is true and how I would go about attaining them.

Update: I finally figured out how to get the five points a while back. I wasn't trying in exactly the right place on the lake to throw the baby. You have to throw the baby in the lake where the pebbles were.
