A little black dog plays in the water and suddenly jumps on the elephants, who just start shaking like they're gonna throw a little black dog in the water, but the little black dog looks like a little bit of a surprise. And then the elephant gets bigger, doesn't it say it's going to get mad and it's going to dump the dog in the water?

It's true the dog was dumped in the water by an elephant. God, this dog is too bad. When everyone thinks it's gonna get mad, it's like it's been a thing of habit.
After a while, the dog plays around the elephant with a little ball, and the elephants play with the puppy with their noses. The dog seems to be too tired to get up on the elephant again.
Elephants are very active this time, getting dogs up. Dogs can't get up there without a moment, and they can't get off on elephants. But the elephant was very subdued and ignored the naughty dog.

Then the staff said that the dog and the elephant were good teammates, that they used to play together, and that all these naughty little tricks of the dog were playing with the elephant. Elephants are of course dogs, but that friendship is invaluable.
