Make bats bigger

Bats have a lot of detail (a higher resolution texture) for how small their model is and players often do not care about them very much. Changing their size wouldn't make them a more useful or interesting mob, but it'd at least let players get a better look at them and make them slightly more thrilling to see.

Today's snapshot introduced the Bee mob, which is a really nice mob and I like the size of it. They're really cute and I love seeing them. I'd love if I could see larger bats in game so I could fully appreciate their texture-work, their behavior and the way they fly straight into lava. It'd be truly beautiful.
