The bit about the elephant is somewhat true, I live in a part of the world where they are in the wild. They are silent when moving and can be moody, one can suddenly show up in a thick forest without you realizing it. They are surprisingly fast at navigating through rainforests. While tigers and leopards are dangerous, they rarely go specifically after people and there are steps to scare them away (like the people in the Sundarbaans wearing masks on the back of their heads). Elephants on the other hand, you can't really discourage them from approaching you, just pray to god that it decides to leave you alone instead of crushing you.
