Bat Update

Bats in real life are super cool and very environmentally import but they don't really do anything in Minecraft.  

My pitch: 

Basic Bats: You can tame and breed bats using glow berries. Tamed bats should be able to carry one item stack for you, like a fox. This feature would be most useful if the bat is given bundles. Tamed bats should also be able to sit on your shoulder like a parrot. 

Big Bats: Most people probably won't find tamable bats interesting enough to go through the effort of messing with this update so in this drop a rare large bat mount can also be added. The bat mount could act more as a paraglider with two "flap" charges that shoots you upward 10 or so blocks. The bat would act an elytra parallel. The bats could have a slot for a saddle/harness that could either be the same as a normal saddle or a special saddle variant found in underground structures like dungeons and ancient cities as well as two bundle slots to make up for a lack of a chest or armor slot. Big bats should be decently rare but if you find and tame two big bats breeding them should have between a 50-100% chance of resulting in a big bat. Other big bat features could be varying flap heights and speed or the ability to connect to a happy ghast and boost its speed by pulling it. 

This bat update would go great with all the other mounts and old mob tweaks Minecraft has added recently!
