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.

Route 12

Route 12.

Sleeping Beauty

You'll need to use your Poké Flute to wake the Snorlax blocking the path here. But stop at that first building and get TM 27 first. It contains Return (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.

New Pokémon

#118 Goldeen	#98 Krabby
Now that you have the Super Rod, you'll be able to fish for more Water-type Pokémon than you know what to do with. So you might wish to ignore the less interesting ones like Goldeen. Evolved form Seaking is fairly tough, but with nothing but a handful of ordinary Normal attacks, she's not that intriguing.	Krabby is a fairly good Water Pokémon, and you can have fun beating things instantly (30% of the time) with his Guillotine technique. But Krabby's real selling point is that he can learn Cut, Surf, and Strength HM's, allowing you to have them all without using more than one slot on your bench.
#116 Horsea	#72 Tentacool
Horsea's evolved form Seadra is a solid fighter, and learns a good variety of Water-type attacks. But you probably won't want more than one or two Water-types on your bench, and there's a variety of better options. Wartortle, Cloyster, and Articuno top the list.	Tentacool mixes Water with Poison types, and learns a variety of good attacks in both (and has a high enough special to make good use of them). Built-in poison attack Acid does damage while lowering defense, which is nice, but Poison types still aren't stellar.
#132 Ditto
Ditto may have the ability to Transform into any Pokémon it faces, but with such weak stats, it's almost not worth the catch. However, Ditto does have one factor that makes it worth it. Because of its Ditto egg group, it can breed with any egg group except for its own and the No egg egg group. Find one with some good IVs, and you'll have an excellent breeding Pokémon on your hands.
