The 1st room of the Rock Tunnel was simple, I got the Repel and beat the Pokemaniac. I also caught a Geodude and I headed to the 2nd floor. On the 2nd floor I beat another Pokemaniac and picked up a Revive. I then beat a Picknicker and yet another Pokemaniac. I then caught an Onix and battled and beat two Hiker and headed to the 3rd floor. On the 3rd floor I battled three Hikers and got an Escape Rope and went to the 4th floor. I beat a Picknicker and then taught Primeape Rock Slide. I picked up a Max Ether and battled a Hiker and a Pokemaniac and went to the 5th floor. I battled 2 Picknickers and picked up a Pearl and battled another Picknicker and left the cave. I skipped the trainers and arrived at Lavender Town where I healed up. I then went back north to battle the trainers outside the cave. One in particular Picknicker said something interesting. I then healed up again.
