Bats don't usually take on prey that are larger than themselves...
So, i think Aflac wins in this one.
Never mess with a duck's young. Trust me. One of the critters chased me half a mile when I didn't see that i was in arms length away from it's little-un. D:
Duckity duck duck duck. If the duck quacks loud enough it will deafen the bat and then the bat can't hear so it goes crazy and flies infront of a moving truck. Simple. *Gives the duck a megaphone* *Gives the duck the plan*
If they were both actually trying to fight to the death I suppose the bat would win if it managed to get i foot on each eye of the duck and wrap its wings around the ducks head ot hold itself in place, but I'm thinking purely because of size if the bat missed it's first strike it'd get done pretty hard.
On another note my cat left what looked like a family of bats skinned and on my door step.
