|Back in Route 2 if you head south from the exit of Diglett's Cave
you'll find 2 Houses.
In the first house a guy is trying to trade a Mr. Mime for an
Abra (in Red & Blue) or a Clefairy (in Yellow).
The next house has one of Professor Oak's Aides in it. If you've
collected 10 or more Pokemon he will give you the Flash HM.
After that house you can find a Moon Stone and an HP Up in
Now it's time to go back to Route 11.
