Referring to an elephant by her, he, and himself. Since when?!
I read these two questions on an English-website.

Q: How do you keep an elephant from charging?

Take away her credit card!

Q: Why did the elephant paint himself different colors?

So he could hide in the crayon box!

Can somebody explain?

Answer

Animals are generally refered by 'it'. But if our relation to an animal is personal, like pets or if we have known them for quite a while now, then it is okay to use him/her.
 The personal him/her are also usually used for animals in Children's books/ poems.

Answer

There isn’t a fixed rule about it. I would say in this instance it’s because it’s a joke, maybe, i.e it’s lighthearted, non-serious, non-literal language. You might find this interesting: https://video.newyorker.com/watch/comma-queen-that-vs-who?c=series

Answer

Daphne - Thanks for explaining it. Those are jokes, by the way.

Answer

Riddle 1:
Charging can mean a lot of things. It can be by the way how an elephant attacks or another term for paying bills in Native English is "charging". For example, (a conversation between a seller and customer):
Seller: I will charge you $100. 
So in riddle 1, it is just a play on words.
