Bucket of aquatic mob

Fish buckets are a form of water bucket with a fish inside them.

Obtaining
A fish bucket can be obtained by a water bucket on any fish mob. The fish bucket obtained will correspond to the fish picked up.

Usage
Pressing with a fish bucket will empty it, spawning the corresponding fish back into the world, leaving an empty bucket in the player's inventory. For tropical fish buckets, the patterns and color of the tropical fish are remembered and stored in the bucket.

Trivia

 * Fish are heavy enough to push the bucket they are in downwards by one pixel.
