An Australian man walking his dog along a creek was astounded and then  alarmed when he stumbled upon a monstrous-looking kangaroo bathing in  the water.

Jackson Vincent managed to snap some truly breathtaking pictures of the  muscle-bound marsupial which appeared to be keeping a close eye on the  interloper who had interrupted its swim.

Based on his proximity to the creature, the young man estimated that the  animal stood nearly six-and-a-half feet tall and weighed around two  hundred pounds.

Although initially quite excited about the encounter, Vincent's  perspective quickly changed when the kangaroo began heading towards him  in what seemed like an aggressive stance.
