route 214 it may be rare catch
uxie,hippotas,hippodon and snorlax(yes he is in platinum).
in the Maniac Tunnel can you find them
You find hippopotas (note I spelled it right) in the maniac dude's cave
You can ask friend for a hipodon mate it with a ditto
A trainer on iron island has hippotas
They are in the maniac tunnel.
in platinum go to snowpiont city there will be a clown to your right [beside the Pokemon center] good,luck
hmm, hippopotas i think u can get from maniac ruins on route 214 but u need to catch every Unown
Have you seen a trainer with one? if so go to your pokedex search for the hippotas and go to "Area"
hippotas is on iron island
where can i find chimchar in Pokemon platinum version
