After picking up the Deep Sea Tooth and Deep Sea Scale on a grassy island, I also picked up the X-Scissor TM and then I went back into the water and Surfed towards a bigger island. I entered the Sea Spirit's Den, but there was nothing of interest in there yet so I went back outside. I spent about 15 minutes battling against wild Tentacool in the area for some extra training, then I headed back south to Coumarine City. I quickly healed my Pokemon at the local Pokemon Center and bought some healing items as well. I headed back to the Coumarine City Gym after that and once I was inside, I started climbing on the various vines throughout the Gym and I defeated two Pokemon Ranger trainers and their Grass-types.
