Pokemon 122 is Hippopotas, which you can find in the cave to the left of Route 214. The more different kinds of Unown you have, the more likely it is to appear.

Under Veilstone City is a small cave where a man is digging. In there you can find that pokémon. But I don't think it's very common, so you must be patient when you look for it.
The prime factorization of 122 is: 2 x 61
Mt. Pyre in Pokemon Emerald is near Lilycove City on Route 122. You have to surf to get there, or make it to the Safari zone. There's a cave where you have to go in and move up, and there you will find Mt. Pyre.
To Find GIGA drain go to the other side of Mt Pyre (Route 122) you are now in route 123 go to a girl facing the trees and she will give you TM 19 but you have to have a grass Pokemon in your party or this will not work.Thanks hope this helpsZattack
