Pokémon FireRed and LeafGreen/Route 12-13

'''You've liberated Saffron City from Team Rocket's mad scheme, and you could probably use a bit of a holiday. We hear the fishing is good down south of Lavender Town, so grab your Old Rod and get set to drown a few worms. You ought to pack the Poké Flute, too. You won't be able to avoid Pokémon duels completely on this trip, but things will be far less hectic. Route 13 is more like a maze than a highway, but it is a pleasant place to walk and enjoy the great outdoors.'''

Sleeping Beauty
You'll need to use your Poké Flute to wake the blocking the path here. But stop at that first building and get TM 27 first. It contains (the stronger the friendship, the more powerful it is). The Poké Flute has the power to wake a sleeping Pokémon, in or out of battle. Pipe a sweet tune to rouse this Snorlax from its rather inconvenient resting place. It won't be very happy about the wake-up call, but when it attacks, you can try to capture it. This is the only other Snorlax in the game, so if you didn't catch the one in Route 16, here's another opportunity. With the way clear, continue south to Route 13. After the Snorlax, get the Super Rod in the 2nd building.
