The Diplodocus trudges in a leisurely fashion through the prehistoric world. It's in no hurry at all, especially as it is on the heavy side. But this colossus doesn't need to be scared of anyone. At that size, nobody wants to mess with it. If it does get angry, it whips its long tail threateningly from side to side. Watch how fast everyone disappears! Now it can get back to its favorite hobby: nibbling branches.
