12 is crowded with 7 fishermen eager to test their newly captured
water-type Pokémon out on you.
On your way you'll find Iron and a TM 16, but you won't be able
to get the TM until you can Surf.
Eventually you'll run into Snorlax, be sure to catch him or else
he'll run away for good (there are only 2 in the game)
Next you'll find a house with a fishing guru inside. He'll give
you his Super Rod! Get ready to drown some worms, we're going
fishing!! During the course of the game, you'll be able to catch
almost every type of water Pokémon with this rod. Be sure to fish
often and everywhere and you'll eventually catch all that you need
to finish with all 150 Pokémon.
Round the corner and you'll turn into Route 13.
