Grasshopper mouse in the size of a blue whale. This creature would be good at destroying this world.
"Displaying bravery against the odds, as night falls he emerges to track down and disarm deadly scorpions. As ancient adversaries, interactions between mice and scorpions have occurred over millions of years, giving the mouse an evolutionary advantage - they have developed immunity to the venom inflicted from a bark scorpion’s sting. They have also developed the ability to convert the scorpion's neurotoxins into a painkiller.
Apart from scorpions this carnivorous rodent is a ferocious predator that also eats grasshoppers, centipedes, but it may even eat lizards and other mice.
These mice have an unusual way of staking claim to their territory and to warn others of their presence – they stand on their hind legs, throw back their head and howl at the night’s sky like a miniature wolf"
