Kangaroo
Boxing champ with built-in trampolines.
Kangaroo vs Cheetah
Tonight's science rumble is set in the picnic meadow, sandwiches evacuated. No snacks were harmed.
Kangaroo
Macropus rufus
Kangaroos cannot hop backward. The contract with physics is one-way.
Grasses and shrubs. They are hoppy lawn mowers.
Cheetah
Acinonyx jubatus
A cheetah's tail is a rudder. It steers mid-sprint like a boat.
They prefer gazelles and other speedy snacks they can outrun.
Who do YOU think wins?

Cheetah
The land-speed record in spots.
