Inês fells all the ducks
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
Inês begins by throwing rowing paddles at the fences, having Nuno retrieve them for her after every throw. She also decides that Nuno can assist with knocking down the ducks, so he throws the paddles a few times as well. She eventually moves on to throwing an empty bucket and a basketball before deciding to try using a hose. After Inês is unable to fell a single duck from the water pressure, she gets the idea to trap the hose in the fence to pull it over, but she neglects to actually tie the hose around the fence and just manages to pull the hose towards herself. She rectifies her mistake, and by pulling the rope, manages to shake the final ducks off of the fence. Inês fells all the ducks in 16 minutes 36 seconds and comes fourth.
