Pufferfish are fascinating creatures, and they have been added to Minecraft! In most Lukewarm or Warm Oceans, you may find one of these fish swimming about. Be careful, however, as you must be aware that the Pufferfish has a built in, biological defense mechanism.
These fish are famous for their ability to inflate their own bodies! Thankfully, this feature has been authentically recreated in the world of Minecraft. These fish look quite small and perhaps unrecognizable at first, but rest assured that getting close to one of these will make them inflate! In the inflated state, Pufferfish have poisonous barbs that will infect the player with a weak poison.
You need a Bucket and water before finding a Pufferfish, but you can find water easily.
With a Bucket of Water, approach a Pufferfish. Press the use key on the Pufferfish to place it in your own Bucket!
This Pufferfish is inflated!

There are a few other examples of fish that will sit happily inside of a bucket. Some of these fish are the Cod Fish, Tropical Fish, and Salmon.
With a Bucket, players can contain all kinds of liquids. With a Water Bucket, players can actually keep Fish alive indefinitely inside of their inventory, which is a very convenient way to transport them long distances. This fish can be found in both Lukewarm Oceans as well as Warm Oceans.
