Little elephant, big plot holes.
It's not explained how the elephants know about cars and clothing, and why they're so impressed by it. Are they supposed to be intelligent, or simple-minded and easily amused? I don't know what the purpose of this book is. There's so many holes in the universe and the story that is told that it doesn't make a lot of sense. The characters motivations are really unclear, and it ends up being really bizarre.

Elephants want to be more like people.
