There are all sorts of different mobs in Minecraft, each of which is actually a big part of the game and adds a lot more to it. Some of these mobs are friendly, while others are very hostile. A lot of the friendly mobs also include animals, such as dogs, cats, cows, sheep, etc. and there are even aquatic animals like dolphins.
By following the right methods, you can also make a majority of the animals in the game your pet. However, what stops this from happening for some players is that the animals randomly despawn. This is especially the case with any dolphins in the game that you might try to make your pet. Here’s a bit more information on why this might be happening to you as well as other players.
Minecraft Dolphin Despawn
The first and most obvious reason behind your dolphins despawning is that you might not have given them a name. Until you’ve given a friendly mob a name, they’ll just despawn and disappear once you go far away enough from them. To prevent this from happening all you have to do is give your pet dolphin a name and it shouldn’t despawn anymore. It is also recommended that you don’t name your dolphins the same thing if you’re keeping multiple of them as pets and/or as part of an aquarium.
If you already knew that and they’re despawning even after you’ve given them a name, you’ll have to make sure that you tend to the needs of the dolphins that you’re trying to prevent from despawning. For example, if you’ve taken them away from their original spawn point and are keeping them at a new body of water, you’ll have to take quite a few things into account. One of these is that they need a lot of room to move and play around in.
Another thing that you have to make sure of is that there isn’t another mob near your dolphins that might attack them and potentially kill them. Once they die, their body will eventually despawn and you might mistake it for a random despawn.
Like this, you have to absolutely ensure that your dolphins aren’t dying if you wish for them to stop despawning. Another thing that might be causing them to despawn in your game is that you might have kept them locked up in an enclosed space like an aquarium without an open roof. These types of environments that aren’t open from the top will stop the dolphins from eventually leaping out grabbing a fresh breath of air, causing them to drown and die.
This is realistic as dolphins need to breathe in real life as well, and stopping them from doing in Minecraft so will make cause their death and make them despawn. Even if doing all of this still wasn’t enough to stop your dolphins from despawning in Minecraft, you could try keeping them attached to something with lead. This will absolutely make it certain that they never despawn, no matter how much distance you put between the dolphins and yourself.
