Where is the Pokémon Crimson? This is where many players are confused, so I will introduce to you the details of the location strategy of Chou Chou Fish. Friends in need can refer to it.
1. First teleport to the pool location as shown in the picture (or walk over).
2. Then walk along the red arrow as shown in the picture to the back of the hillside pointed by the green arrow.
3. You will find a cave here, go in.
4. When you fall down, you will reach a relatively spacious cave. After landing, look due south. There is a hole going down. Go in.
5. After entering, you will fall into two pools connected by a small hole. This is the refresh point of the ugly fish, which will appear in both pools.
6. This should be the only wild ugly fish breeding spot in Beishang Township. Ugly fish can be found in both pools. If it doesn't come out, you can clean up other nearby Pokémon, and then it will be refreshed.
7. Also note that the fish here like to swim at the bottom of the water. It is recommended to hold down ZL to find monsters. A large number of them occur here, but picnics are not allowed in the cave, and there are also mud loaches of the same water type in the pool to interfere. Very troublesome.
