Kangaroo
Boxing champ with built-in trampolines.
Kangaroo vs Koala
Tonight's science rumble is set in the visitor lawn, now closed for SCIENCE. 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.
Koala
Phascolarctos cinereus
A koala's fingerprint looks a lot like a human's. Weird science.
Almost only eucalyptus. Most of those leaves would upset other animals' stomachs.
Who do YOU think wins?

Koala
A sleepy specialist with surprising claws.
