Butterflies, Milkweed, Fireflies, Jars, New Death Animation..

Minecraft should add butterflies and fireflies to the game. 

Like milkweeds and a butterfly biome to go with. 

they should add jars so you can catch the butterflies and fireflies and have the ability to pin butterflies to your wall, as well as place the jars down while crouching or something like that. 

That would be very neat along with a death animation that spawns butterflies instead of the white cloud or smoke.
