After surfing to the right of Wakaba Town, talk to the
fat guy when you reach dry land. He'll give you a new map card expansion
that has the map of the original Pokemon World from Red, Blue, &
Yellow (Kanto).
Next you'll enter a cave that has a waterfall. Surf up
it and then down the other side to get out of the cave.
TM 37 - Sandstorm
Once you exit the cave you'll find a house. Inside an
old lady will give you TM 37, Sandstorm, for talking to her.
TM 22 - Solarbeam
On Route 27, you can Surf off the bridge to find this
TM. Make sure you bring a Pokemon with Whirlpool along to get it though
because there is a whirlpool blocking the path to get to it.
Route 27 and 26
Next you'll surf east some more and encounter more
trainers when you reach land. There's new Pokemon to catch and trainers
to fight.
Before heading onwards, there is a house with a woman
who will heal all your Pokemon for you.
Head north and you'll eventually reach Victory Road.
