Myxobolus

The myxobolus shekel is the smallest animal on the planet. Here’s why it should be added to Minecraft: it could spawn in coral reefs, near groups of fish. They’d be passive at first but attack when provoked. They are about the same size as a tadpole in this game, since their real size, 9 micrometers, would be too small for the game. They drop some experience on death, and could drop myxobolus tentacles, since myxozoa, the class myxoboluses belong to, is related to jellyfish. These tentacles would be used to make myxobolus bows using a bow, a tentacle, and an amethyst shard. This bow would have a longer reach than a regular bow, and the arrow you shoot will always come back to you, unless it falls on a cactus or into lava. To make things harder, myxoboluses only spawn in groups of 2, with a 6.39% chance of spawning naturally. You can breed them with salmon, cod, and tropical fish (and sardines, if they ever get added). I think this animal, the smallest of them all, should be added.
