I healed my Pokemon in Petalburg City's Pokemon Center and I bought some more Poke Balls at the local Poke Mart as well before heading out to Route 104 again. I walked north and I entered the Petalburg Woods again. I battled and caught a wild Silcoon and Cascoon as I moved around the forest path, then I eventually met a Devon Corp. employee who was being harassed by a Team Aqua grunt in the middle of the forest. I battled against the Team Aqua grunt and beat his Poochyena with Taillow, then I obtained a Great Ball from the Devon Corp. employee and I continued to wander north. I exited the Petalburg Woods after beating another Bug Catcher, and I arrived outside of the flower shop on Route 104.
