Huh, that is a pretty funny looking dog, ain't like any puppy I've seen before. That said, this is the most typically Australian photo you've taken so far XD! It's sad to hear that so many Roos are being injured and killed on the roads, though as you say, it's nice that groups like these will help out those little ones.
Echoing what someone else said in the comments, I do think you should've brought this little Joey back home. You have many Legos and Oreos that people could steal. I've seen Roos box each other before, and I can't imagine what a fully grown one could do to a human intruder. Plus, you could also employ a grown Roo to beat the shit out of Grouchy the next time he misbehaves. I'm sure he'll work well as a punching bag.
I don't think Grouchy would stand a chance against a full grown roo. The big Red's get huge, seven feet, and are very powerful. Hmm, that makes me think...Kangaroo/Grouchy fight club, streamed live to hive! Sell tickets...Merchandise. Lol.
Ah, but Grouchy's upper-hand is that he's tiny, agile, and very cunning. Just slip up the Roo's leg, and punch him right in the nuts. That should do well to incapacitate anyone! A Roo v. Grouchy fight is something the internet needs, and are dying to watch!
Lol, a bit of a low-blow, but what choice does the little green bugger have right?
The first rule of the Fuzzy Fight Club, is that there are no rules. Nut punches are welcome! It'll help level out the playing field by quite a bit... Bloody Roos won't know what hit 'em!
I almost feel sorry for them.
Nah, I'm sure it'll be fine. If there's one fact I know about Australia, is that you bastards have balls of steel. It takes quite a lot to live in a hell hole like that XD
I mean, just look at Australian Stig's chap...
Lol!
