It's the fact that they're mice, yet so different from other mice, that adds to their hardness. It's against-all-odds, against intuition, all-out aggression, savageness, head-mentalness and brutality that makes the Grasshopper Mouse the machine it is, DESPITE the fact that other species of mice...
Nope. Both mice know that they go into the fight with a good chance that they will not only be beaten, but not allowed to run away, instead being killed and then eaten. And both mice still go for the fight and continue fighting until they win or they die. No running away, no retreat. Hard.
I assume you'll be able to persuade all of your 'friends' to the same opinion too? Would be a travesty for the Mouse not to win just because the wolverine looks a bit like a badger.
Wolverine doesn't have enough head-mentalness about it for me. Named after a wolf, yet doesn't even howl? Nah.
For fans of survival attributes too - the Grasshopper Mouse lives in temperatures ranging from below freezing to almost 50 degrees Celsius.
The MOUSE is known to take on, and KILL, other rodents three times its size. How does it do this? By crushing in the back of their skulls, usually killing within ten seconds of initial attack. And then howling to celebrate. And then eating them.
