Rock Tunnel

Description
Make your way across the maze-like tunnel and find the exit. Battle against multiple trainers, wild pokemon, and a giant Onix! Can you save the old man and finish his quest for a shiny Voltorb? Or will your spend your days on the cave training your pokemon? Upon entering, if you do not have a pokemon that knows HM Flash, the giant Onix will imediately throw you out.

You cannot enter the cave without HM Flash so here's how:


 * 1) Beat Diglett's Cave to get HM Cut.
 * 2) Use HM Cut on Route 2 to get HM Flash.
 * 3) Teach a pokemon that can learn HM Flash and your ready to go.

Story
You are still in search of Joey and Maruto, so your best bet is to look for Brock and Team Rocket. They seem to like caves, so you decide to explore the nearby cave.
