If you had to fight one of the following to death which would you choose?

I choose the Gazelle. Platypuses have poison. Armadillos, 50 is too many. 70 Pigeons too much crap all over the place and they're like flying rats. 100 Squirrels, its like 100 jumping rats. 250 mice, I hate mice, they smell and I don't want to touch them. 25,000 fire ants, I would day for sure and they would kill me instantly if they all bite me at the same time, even 20 at the same time. Gazelle is more fun I guess because it's big enough to wrestle with. Although, I would first have to catch it, but if it wants to fight me I would wait for it to go near me and I'd pounce on it like a lion and keep it on the ground then punch it to death and get a headlock maybe.
