Animal Crate

HOW THEY WORK

• Right click an animal with a crate to store them in the crate (This makes the crate very heavy, you'll have to put it on your back)
• Place it on the ground like a normal block, and shift-rightclick it to let the animal out. This destroys the crate.
• If you want to pick up the crate, simply use an axe to break it. If there is an animal inside, it'll stay in there.
• The crate when in your inventory will say what is inside
• When placed in the world or right clicked the animal will make a noise to tell you what's inside.  
• Now you can load your animals up on your ship and sail away! Or it gives you a quick and easy way to get a single animal across harsh terrain on your back (Although I already used the Udary mod for this purpose, never hurts to have options)

FUTURE PLANS

This is just a simple mod I whipped up to fill a need, but I have a few ideas I'll likely implement in the future

• Metal Cages – Always needs to be carried on your back, even when empty, but doesn't break when opened
• Visual cues – Labels and potentially glimpses of the animal inside the crate, so you don't have to pick it up or hit it to know what's inside. 
• Multiple Small Animals – Chickens and bats don't weigh much or take up much space, may make it possible to carry multiple in a single crate. 

(WARNING: Don't release the animal when the crate is beside other blocks, the animal may suffocate)
