Clothing and hairstyles are expensive. Also, I always wondered where Pokecenters got their funding. Turns out they have a complete monopoly on everything you and your pokemon could ever need! Of COURSE you’re gonna go in and get all healed up. Might as well grab some Paralyze Heals and a new hat while you’re at it. Genius.
Is Meowth in the game? I don’t know. Oddish is, so that’s pretty cool.
