Bucket Buddies

Bucket Buddies is a resource pack that makes all buckets 3D, including the fish/amphibians inside them!
Not only that, but it also animated not only the liquid inside them (water and lava only) but it also makes the animals blink! (I know that fish don't have eyelids, but it is still cool)
If you are like 99% of the Minecraft community you probably carry buckets of axolotls everywhere you go, then this pack is for you since it brings more life to the still 2D sprites.
They now pop their heads out of the buckets and blink, giving them more life! (This applies to all animals)
Example of the blinking animation:

Enjoy!
