Many wild Critters have camouflage or coloring or other protective appearances. Rhinos are noticeable, and We like it that way. Young Predators sometimes make the mistake of interrupting Us in our routine. Rhinos may appear to be good targets. We make snuffly sounds to warn them, but no, they persist in being comical.
And then they learn the consequences of taunting two-ton Critters who are armed and amazingly fast.
Their parents just roll their eyes, having done the same thing in their wilder days.
