Certain Pokemon in Sword and Shield have specific criteria that you must meet in order to evolve them. Poulpaf is one of these Pokemon. While it's possible to track their evolution, Krakos, later in the game, you can also evolve the Pokemon using the method below.
How To Evolve Octopus Into Krakos In Pokemon Sword And Shield
You can catch Poulpaf on Route 9, where they'll be between levels 39 and 43, or you can try your luck in a Max Raid Battle in the Wild Area to catch them sooner. To evolve in Krakos, Poulpaf needs to know the provocative movement.
It would usually learn taunt at level 35, so if you catch an Octopus that's higher than that, but you don't know the move, you can go to a Pokemon Center to help it remember the move. When the Poulpaf knows the move, just put it in your party and you can level it up until it evolves. You only need to level once after learning Taunt, and it will scale.
If you're patient, you'll be able to catch a level 50 Krakos soon after you upgrade your Rotom Bike device that allows it to travel on water. Krakos also appears as a strong spawn in the Wild Area invader later in the game.
