The Odd One Out

Deep in the forest, a trial is held for "the Odd One Out". Animals gather here to discuss the creature that confuses every species. The leopard is the first to leap onto the boulder. Flicking its tail, it speaks with sarcasm, cold vertical pupils full of disdain: "I have observed them. That thing is a joke of evolution. They originally had four legs, which should have been their prime time for running at full speed, yet that is the weakest period of their whole life. They don't even have the ability to escape predators." The ostrich flapped its wings, with a hint of arrogance in its tone: Who are you talking about? Two legs work perfectly well, they finally realized how great two legs are. It's just that they can't run as fast as me. Just then, old baboon steps forward, his eyes full of awe and pity: "None of you have seen their twilight years. When shadows stretch long, they suddenly grow a third leg. That is the most unsteady period of their life, but also the most dangerous and unpredictable time for them." From the side, the kangaroo touches its strong tail, mutters thoughtfully in a low voice: "I know that feeling, an extra pivot really helps you stand more steady. But what's strange is, our 'third leg' is made of flesh, but theirs grows out from outside the body……"
