None - Pal Park from 3rd Gen.
You can't. But you can trade with someone who has a treeko!
You can't.
The forest in Pal Park
evolve Treeko or trade over wi-fi
you cannot get a treeko in platinum but you can get it if you migrate from leaf green.
you can't get it in the game unless you have pokemon R,S, or E. You use it for the pal park.
Right get Emerald Sapphire or Ruby then get treeko and evolve it., OR Trade.Or otherwise no
Migrate from a gameboy game it can be from Saphire, but you'll need to evovle a treeko.
I'm gonna trade from my platinum treeko and piplup (i migrated treeko from my ruby to my platinum) so it doesn't matter but if i were u which i would pick tepig. XD hope this helps.
No, because, TREEKO DOES NOT EVOLVE INTO TROPIUS AT ALL.
Treeko is a grass starter Pokemon in Pokemon versios. Ruby, Sapphire, and Emerald. GBA
get at TREEKO! TREEKO HAS AND ALWAYS WILL NOT ONLY BE THE BEST GRASS POKEMON BUT MY FAVORITE AND THE ABSOLUTE BEST!
