on route 214.the Pokemon is hippopotas.
Go down Veilstone city and if so you could go to the spring path it will be easier
The Pokemon #122 in the Platinum Pokedex is the Ground type Pokemon known as Hippopotas. The Pokemon is quite rare. In the Soloceon Ruins, you can catch tons of different Unown. Well, in the route below Veilstone City, you can enter this tunnel. Depending on how many Unown you have caught (note that they MUST be different), the tunnel will grow. That increases the chance of finding a Hippopotas. Another option (though I am unsure if it's accurate) is to battle somebody in Iron Island, which can be accessed by sailing a ship in Canalave City.

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.
Mr. Mime is #122 in the national pokedex, and it is a Psychic-Fairy type Pokemon.
Hippopotas.
A wild guess would be Survey Number 122
Well, isn't that just a happy little question! To turn 122 into a mixed number, we divide 122 by the whole number it represents, which is 1. So, 122 as a mixed number is 122/1. Remember, there are no mistakes, just happy little accidents in math!
