He's mega buff and mega tough but we promise he's not on steroids! Roger is a hard-nut kangaroo, and the most muscular we've ever laid eyes on. He lives in a wildlife park called 'Kangaroo Sanctuary' in Alice Springs, Australia. The pumped up kangaroo is, hilariously, quite the show pony, loving nothing more than posing for photos with tourists. And as you'll see, he always makes sure his massive muscles are firmly flexed! Check him out!
