A mighty bull was stretched out comfortably on a bed of straw inside his stable.
Meanwhile, there was a tiny mouse in the straw, and as the mouse nibbled on the straw, she also nibbled on the bull's leg.
"Who did that?" roared the bull. He shook his head angrily, gesturing with his horns, and he finally sprang to his feet, stamping and snorting, looking everywhere for the enemy that had wounded him.
The mouse scurried into her mouse-hole, laughing to herself. "Who would have thought a little creature like me could win a fight with someone so much bigger!"
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 199 in the book, which is Perry 353.
