On Pokemon Emerald go to battle frontier, after you beat the Elite Four then go to the botom right most part of the frontier.
You will find a tree that moves, use the wailmer pail on it and a Sudawooda will appear. Kill it or catch it. I suggest you catch it, then surf left till you find a cave the cave is full of Smeargles.
The cave is called Artisan Cave, and the Smeargles in it are level 41 and up.
You can also find a Smeargle in Diamond and Pearl at route 212 - north , it is very rare and you need to have a Pokedar to catch it. You get a Pokedar after you beat the game from Prof. Rowan.
On Soul Silver you can catch one by the ruins of Alph and by going to the Safari Zone and going to the plains area there and run through the grass, it also works for heartgold.
On Pokemon Crystal, it is actually very easy to find Smeargle. Go through Union Cave and use the ladder to go to another map. Once there, surf through the water to the other side and keep going until you get to the opening. Once you get outside again there will be a grassy area to the left of your screen. Just walk around until you run into a Smeargle (you can also find a Natu in this area). I suggest having a Pokemon that knows Sleep Powder and an Ultra Ball or a Master Ball, so you can catch it without wasting its Sketch move which can only be used once.
You can find Smeargle in route 212 using the Poke Radar.
Smeargle can learn transform in two ways. In Gen III if you put ditto to sleep then have use transform it will fail, and smeargle can sketch it. In Gen IV onwards the Smeargle must know Dig, Dive, Fly, Bounce, or Shadow Force. Have Ditto transform into Smeargle and Smeargle use 2-turn move (Ditto must be slower (use the lagging tail). Transform will fail due to lack of target. next turn, have Smeargle use Sketch on Ditto, and give ditto a berry. Sketch will successfully copy Transform
Battle a Pokémon that can use wish(eg Natu or Xatu), and get Smeargle to use sketch when it uses wish.
It doesnt evolve
You catch Smeargle ;)
smeargle does not evolve
No, Smeargle is not a Legendary Pokémon.
well, apparently, your smeargle has to be paired with another smeargle of a different gender or a ditto. If you paired the smeargle with anything else it wont work.
Smeargle is a Normal type pokemon.
Enter a double-battle with smeargle and a Pokemon with spore. Have that Pokemon use spore and have smeargle use sketch on him/her.
No, Smeargle does not have an evolution. It's a one-stage Pokemon, meaning it has no evolutions or pre-evolutions.

you don't
Simply put, its a cave which is filled with tons of Smeargle. Which is fine cause Smeargle are awesome :D
when you capture smaergle, there isn't really something important for you to do. you could train it, but there isn't much to do after u catch smeargle.
