Pokémon FireRed Tips

Bonus Moonstone!
There are actually two moonstones in Mt.Moon.
When you reach the super nerd who will fight you for the 'helix fossil' or the 'dome fossil', walk back to the entrance of that small cave area.
Walk to the right and theres a small area that you can fit into. (not that you should still be able to see the scientist/nerd, if you can't you've gone too far). There will be a rock at the end. Press 'A' and it'll say, 'You have found a Moonstone!'.
This is the final one neccesary to evolve every moonstone evoloution in the game.

I have a few more if anyone is interested, i have alot of spare time and alot of Pok'e'mon.
