The only possible way would be to trade it over from another one of your games or from a friend.
You can not get groudon in Pokemon pearlYou can get it through migrating from ruby, sapphire, or emerald.
the only way to get groudon is to either import it from Pokemon sapphire/ ruby/ or emerald, OR, trade it from pearl/diamond/or platinum.
You can't
Groudon isn't in Pokemon Pearl. The only way to get Groudon is to trade it from the GBA game, via Pal Park, or to cheat.
groudon is in pal park in the mountain area
There is no real way to get groudon, but you can just migrate it, or have a friend trade it to you.
No, you cannot find a GROUDON in Pokemon Pearl. Groudon is only available directly in Pokemon Ruby and Emerald versions. You can trade from the third gen games via the Pal Park, but that's it.
if you have action replay you will get to pick a pokemon so groudon is a hard pokemon you need the red orb for groudon on pokemon soul silver version or pokemon heart gold version but use action replay on pokemon pearl,diamond,platinum
You can't Find Him on Pearl he can be traded from Heart Gold or Soul Silver but you can't catch groundon on Pokemon pearl i hope i helped. :)
in Pokemon pearl u get glameow,in Pokemon diamond u get stunky.so no stunkey in Pokemon pearl,[i tried this, cacthing stunky].
There is no such thing as a "super form" for Groudon, Kyogre, and Rayquaza, and there is no way to obtain these Pokemon in Pokemon Pearl without the use of an external cheating device. However, you can capture these three Pokemon in Pokemon Ruby, Sapphire, or Emerald and import them to your Pearl game through Pal Park on Route 221.
Groudon doesn't show in Pokemon Sapphire just like if you buy Pearl, Dialga won't show up in it.
