Get In The Bucket Mod

With this mod, you can catch any mobs in a bucket with a simple right-click! Just approach a creature and use the bucket - the mob will be inside. If you need to return to normal interaction, simply crouch.

All mob data is preserved when placed in the bucket and fully restored when released back. Using commands, you can even manually set entity parameters through the EntityData tag.

In creative mode, collecting mobs in buckets works as deletion, and placement - similar to using spawn eggs.
