This is mod is my first attempt so please let me know of any errors or bugs on this thread. The mod adds enderchest access to cows, pigs, sheep, bat, and rabbit(1.8). The purpose is to add an interesting new aspect allowing instant access to your personal enderchest virtually anywhere. I plan to improve the system to make it an emergency access chest. I will figure out a way to balance the access to the enderchest if people do not like the instant access from the start.
Right click a cow, sheep, pig, bat, or rabbit. ender chest opens up to place or take items.
I have tested your mod. I like the idea but I believe there should be a cost for having access. i also noticed that it was missing a couple animals like chicken and squid. I also suggest adding zombie pigmen just so they can be accessed from the neather. I believe this could add more to the mod.
