Kraken is a boss mob that currently spawns in the ocean biome. It was added in the "Vamos a la Playa" update. It drops a kind of leather (kraken skin) used for the diving suit and the super hammer. The kraken is able to climb onto bridges.
The kraken is impossible to outswim, and it can easily kill you if you are holding a weapon. Because of this, combined with its high health, the kraken is arguably the most difficult mob, beating even the Lava Dragon. Fortunately, there is no quest to kill a kraken, so you have plenty of time to prepare.
When wearing a Diving Mask, the kraken moves at the same speed as you do. Because of this, you can lead it to the river with relatively low effort. Keep in mind that you can still get hit; if this happens, you should immediately move to land. Once the kraken is in the river, it cannot escape as easily. You can now hit it with a sword. Note that you will still need to move "up and down", similar to how you would kill a dragon. You will still get hit occasionally (most likely) so bring several bandages. If you use this method, be prepared to have other players try to steal your kill. If you kill a kraken at the edge of an island, you are less likely to have your kill stolen, but you are more likely to die or have the kraken escape.
One very efficient and easy method to kill him is to build a three by three cube anywhere in the ocean perferably near the beach. This is more difficult in the recent versions, since krakens can now grief buildings; it is recommended to use reidite walls, and even then you may need a wrench (note that the kraken has 50 building damage, compared to the dragon's 90 building damage). You then fill in the right and left side with walls then you place 3 doors in the middle. Then you lure kraken inside and use a spear or pitchfork to close all 3 doors the kraken will then be efficiently trapped inside. Then you can easily kill it by swinging through the walls; but be careful not to open the doors.
There are a couple of other ways to kill the kraken that are relatively easy, but require some preparation. One way is to use a boat and pirate hat. Then kill the kraken much like you would kill a dragon on a sled. Another way is to use a bow. The kraken takes 30 gold arrows, 20 diamond arrows or 10 amethyst arrows. It takes 7 reidite arrows or 5 dragon arrows, but you need kraken skin to make a reidite bow (so you will probably use amethyst arrows to kill the kraken for the reidite bow).
In general, you only need 1 free inventory slot, as the game prioritizes kraken skin over fish. However, you need 2 inventory slots to get fish, and 3 to get scales.
