It only contains Smeargles.
there is no thing that i know of
smergle is in there and also outside of it there is a soodowoodo
all smergale. very ussless they are.
There is a sudowoodo to the right of the battle palace near it is some water you can surf on go down and into the cave this is artisan cave the only Pokemon that is found here is smeargle other then that you can't find any other Pokemon in the frontier.
its not under a boulder its smeargle and there everywhere in artisan cave.
the artistan cave in Pokemon emerald is at the south of the battle frontier, it is also a place where you can catch some really strong smeargle.
you can get it in the wayward cave, battle frontier shop, or a high level Pokemon that has the ability pickup
u can buy them in the battle frontier exchange corner for 1bp or find them in artistic cave.
you go to your town and use surf and go through the cave and keep going and you will get there
First you catch sudohoodo at battle frontier and you do surf ,you cross the waterfall and a few steps later you find a cave. It is ARTISAN CAVE in this cave only this Pokemon exist
NOTHING! Its just the only place where you get smeargle. Plus there are sweet items in there like PP up. I heard on a certain website that you can get mewtwo there, but I'm not saying that's true.
its a cave on the battle frontier island i think in emerald. you have to water a sudowwodo and it will attack you and you will battle it. then you can capture it watever. and you i think surf to a cave where only smeargles live. kinda boring other than capturing those two rare pokemon.
