Mobile tank-traps, with a top speed (afaik) of 80km/h (50mph).
I've been in a car when we hit one (slowly - it was dark and we were being careful. edit - though clearly not careful enough). The car was messed up but mechanically ok. Driver decided to "put the wombat out of its misery" and hit it in the head with a crowbar. He said it was like hitting a rock with a carpet on it. The wombat didn't notice the blow and scooted off into the bush. We all felt reeeaaally good about that camping trip
Delicious. Also their hind feet have massive claws of disembowellment.
Eastern Grey kangaroos aren't very scary (but are host to ticks that ARE scary - especially for dog owners). As car-traps they're scary, though not as scary as wombats. I've been walking the dog in Canberra through the pine forests there (before they all burned down - HA!). I heard a freight train rushing towards me and looked up to see a bush explode and turn into a grey furry bundle of face, tail and big claws as the roo my dog was chasing blasted past me. I tried to do my best impression of a tree (bigger than the one it'd just atomised, maybe one with rocks in) and waited for the world to end. The dog was lucky that, in the years we lived there, she never cornered one - otherwise she'd be dead.
Red kangaroos are too scary. Great
on postcards and in the distance. Otherwise I back away slooowwly and get in the car. Like something out of Jurrasic Park, but with fewer plants and more sunshine and desert.
Mythical. A litmus test for tourists: if they turn green they put no effort into researching the country before they came.
Delicious. An excellent source of Vitamin B. Less is more. Shouldn't be eaten like jam, should be eaten on toast. The chilli comparison was a good one.
