Not all Pokémon run into the grass Pokémon Sword and Shield. Some take a long time to locate and you should do your best to add them to your location. For example, if you want to add Barpau and his evolution Milobellus to your Pokédex, you have to spend a lot of time fishing.
You can find Barpau in Pokémon Sword and Shield, but you don't have the best of luck. It spawns on route 2 and you have to throw your fishing rod into the water along the route to wind it up and fight it. Unfortunately, you only have a 1 in XNUMX chance of capturing it on this route. There are the ideal fishing spots on this road west of the professor's house. To reach them you have to use the Motisma Bicycle upgrade in order to cross the water.
This percentage of luck means that you have to spend a lot of time at a watering point along this route to find it. Since he has a low probability, he is somewhere between level 37 and 40, so it's a decent battle. Barpau is a pure water type, so you avoid using the electric and grass types to combat it, so as not to pass out. Once you've captured him, turning him into Milobellus takes work.
Add Milobellus to your Pokédex. You have the option of finding a Prism Scale and keeping it for the Barpau. While it contains the item, trade it with a friend of yours and it should evolve into the Milobellus. I hope your friend has the good faith to offer it to you. You should have it in no time and add it to your collection and list.
You cannot locate Milobellus in the water. You need to swap it with the Prism Scale.
Given how long this process can take, locating a Prismatic Stone and trading it with a friend seems like the best way to add Milobellus to your Pokédex.
