Kangaroo
Boxing champ with built-in trampolines.
Kangaroo vs Hyena
Tonight's science rumble is set in a giant zoo clearing at high noon. 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.
Hyena
Crocuta crocuta
A hyena's whoop can travel 5 kilometers.
They hunt more than they scavenge. Wildebeest, zebra, leftovers — in that order when possible.
Who do YOU think wins?

Hyena
The bone-crunching comedian of the savanna.
