At the start when professor birch is getting by a poochyena. Go to his bag and click on the pokeball on the left and you get Treeko
First you must beat the game (which includes defeating the Elite Four and Beating Red, and have the national pokedex). After you get Charmander Bulbasaur or squirtle from Prof. Oak, you can see Steven Stone in Sliph. Co building. He will ask what is your favorite crystal colour, blue, red, or green. Blue gets you Mudkip, Red gets your Torchic, and Green gets you Treeko. To get Sceptile choose the Green crystal. Steven will give you a Lv5 Treeko. Level it up to level 16 so it evolves into Grovile. Level it up again, but this time up to level 36. Grovile will evolve into Sceptile (You can only choose one crystal from Steven, by the way).
You can't catch wild Treeko in Pokemon Emerald. You need to choose it out of the three Starter Pokemon that are offered to you at the beginning of the game: Treeko, Torchic, and Mudkip. to see it, battle rival or other trainer
you must trade mudkip from another Pokemon emerald, Sapphire, or ruby
two ways 1 u dont or 2 start over
The starter Pokemon for Emerald are Torchic, Mudkip, and Treecko. Their second stages are Combusken, Marshtomp, and Grovyle. Their final evolutions are Blaziken, Swampert, and Sceptile.
You can only catch treeko as a starter Pokemon or fight it on your rivals team if you choose mudkip.
