How do you get past the rocks in Rusturf tunnel Pokemon Ruby?

You can't get past the rocks in Rusturf Tunnel in Pokemon Ruby just by walking through them! You need to use a specific item. Here's how to get past the rocks:

1. Get the Strength HM: You'll find the Strength HM in the house on the left side of the Rusturf Tunnel entrance (the house with the well in front of it). Talk to the man inside to receive the HM.

2. Learn Strength: You'll need to teach Strength to one of your Pokemon. Go to the Move Tutor in your Pokemon Center and select "Strength."

3. Use Strength: Now, stand in front of the rock you want to move and use Strength. Your Pokemon will push the rock out of the way, allowing you to continue through the tunnel.

Note: You can use Strength to move rocks throughout the game, not just in Rusturf Tunnel!
