Only Wailmer is new. While his evolution in Wailord is impressive in terms of HP and height (base 170 HP, tallest Poké in the game), he’s not that good of a Pokémon in general.
Route 122 can be found by Surfing just off to the south of the Safari Zone, the pier being next to where Team Aqua/Magma were gathering earlier. As you prepare to jump onto said pier, first go far to the west and Cut down the tree to eventually find a Zinc . Now go and jump onto the pier.
Leap into the chilly waters. Not a lot on Route 122, though; just Surf to the south-central side of the mountain and enter.
