You get one month to prepare. For the geese, you only can use your bare hands and all three will come at you at the same time. For the bear, you can use any one weapon invented before 500 AC.
You receive $100,000 for each goose killed, or $10,000,000 if you kill the bear.
Well, it’s about me specifically, not someone else. I know if I stomp on a goose hard it’s going to do damage, but then again I can only attempt it so many times before exhaustion, and there’s the whole issue of what the other two are doing during that movement. If I grab a part and bend it a way it doesn’t go, that’s more reliable and repeatable, but I’d have to have the chance.
My actual plan would be to not stop moving, bat away the attacks I can, protect my eyes, and take any opportunities as they come.
With the bear, I spend the month training with the spear, and wait for the bear to come to me. If it impales itself it’s a matter of strength, weight and technique to keep myself on the not-deadly side. The thing I fear most would be it managing to swipe the spear out of the way and then close on me, in which case I die painfully. If it goes well, I come out unscratched and set for life.
