If there is watermelon, why isn't there firemelon and airmelon and earthmelon. You know…the elemelons.

@Meshelly In Chinese, there is earthmelon (土瓜) but it’s what we call cucumber.

What they call watermelon (水瓜)we call loofa.

For extra element credit, there’s wood melon (木瓜), a kind of quince.

What we call watermelon they call western melon (西瓜).

This is the best thing I've read all day. Thank you. @wrenpile
