I caught a Wobbuffet inside of Dark Cave and I headed back to Blackthorn City after training for a while since I wanted to swap Pokemon at the Pokemon Center. I headed back south to Route 45 and my Slowpoke finally evolved into Slowbro upon leveling up while I battled wild Pokemon. I decided to teach it Avalanche since it needed an Ice-type move and it would be easier to beat Clair's Dragon-types with it. I headed back to the Dark Cave and trained inside for almost an hour against the many wild Pokemon. I picked up some items inside as well including some BlackGlasses from a guy inside, then I headed out after training not just Slowbro, but my whole team as well. I healed my Pokemon and went to the Gym.
