As part of its ongoing efforts to promote every single Pokémon out there, The Pokémon Company has shared special content dedicated to Meowth:
Did you know? When visiting a junkyard, you may catch sight of Meowth having an intense fight with Murkrow over shiny objects. It loves coins, so if you give it one, you can make friends with Meowth easily. But it’s fickle, so you can’t count on that friendship lasting.
