pachyderm
A group of big, bony animals that include elephants, rhinos, and hippos. They all eat dirt and laugh at you.
Elephants, rhinos, and hippos are all pachyderms. They're like the cool kids of the animal world.
Why do they call them pachyderms? Because they're all big and dumb.
The pachyderms came to town. The whole city was terrified.
