Minecraft has gone through several changes over the years the game has been released, throughout those changes there have been many mobs that have come into view. From Guardians to Foxes, and even Polar bears and Pandas. A new mob has been announced in one of the latest snapshots for Minecraft. From the official site
On August 22, 2019. The new Bee mob was revealed in snapshot 19w34a. The Bee had a few items and blocks included with it; like the honeycomb, The Beehive, and Beenest, crystallized honey, and a bottle of honey, restoring 6 hunger points in-game. It was a nice addition added to Java edition, but no plans have been made yet to add it to console, or Bedrock Edition/Pocket Edition.
Around a week later on August 28, 2019. Snapshot 19w35a came out, with some small changes to the bee’s behavior in-game. They now avoided water, for a more realistic touch on them. And if you were to hit one in-game, all nearby bees would become hostile, their eyes turning red, and attempt to sting you if successful they would poison you, and the bee or bees would die a little later after stinging you. Bees also now follow you if you hold a flower, and if it was hostile towards you, it would become passive once again after having any type of flower in your hand or Hotbar. They can also be bred with flowers, allowing you to make an easy honey farm.
Bees can also be farmed for honey as well, with the Bee nest, able to be craftable and used for Bees. Another action that Bee’s can do is collect pollen and bring to a home hive, or their hive, and create honey, being stored in their hive. The bottle of honey also was fixed to not replenish as much hunger points, only replenishing 2 hunger points.
A problem that most people have is, “The mob is that it is too large to be a bee, if they made it smaller it would be perfect.” As fellow interviewee’s Graham Morcom and Amoni Johnson have said over the topic.
Overall, people are hyped for the new update that includes bees in it. Piecing together that the main focus on the update will be based around insects/bugs. As the hype for this theory keeps up, more and more fans have created conspiracies around the snapshots, and the update itself. But we will not know until the update is finally shared from Mojang.

The Honeycomb can be used to craft a Beenest with; three Honeycomb, and six wooden planks of any kind. The honeycomb can also be used for making Honey Bottles.

The Crystallized Honey currently does not have a use, but most likely will in the near future of Minecraft’s new (Literal) Bug update.

The Honey Bottle can be used to increase your hunger points. As said, they used to replenish 6 hunger points but were fixed to replenish 2 hunger points instead. This can be crafted with Honeycomb’s, and a bottle.
