I'm really into caring for my Pokemon, but I keep running out of Poke Beans. How do you get more?
Youget 12 random beans daily from the cafe inside the pokecenter. Additionally once you've cleared the second trial of the second island, you can use PokePelago to gain more.
When you buy a drink at the cafe then the person there will give you some. I'm pretty sure it's about 12 of a random color, but I may be wrong
