Where is the guy that trades you his Mr Mine?

First,its a mr.mime,and the way I get to it (also,he wants an abra for it) is to go to Pewter city,then go towards the enterence it Viridian forest,you will see a tree that can be cut,use cut,then go south (oppposite of the cave) until you see a house (not a building a house,but find the building and a proffesers aid will give you flash if you caught 10 kinds) the guy will be in the house,the higher the abra,the higher level the mr.mime.hope I helped

To get a Mr. Mime you must first catch an Abra to Trade it for Mr. Mime. Go to Digglet's Cave and cross it. Come out the other end then head south and you will see a house go in. Talk to the kid there and he will ask you if you want to trade your Abra for his Mr.Mime, trade. After the trade talk to Prof. Oak's assistant to get HM5 Flash (you must have caught at least ten Pokemon, which you probably have). Use it to cross Rock Tunnel. Then go down farther to get other items.

So, go to Pewter city. Afterer that go to virdian forest. Then you will see a tree which you can cut. Just cut it and go in the direction opposite to the cave.you will see a house, not a building. Go inside the house if you have an abra. Then the guy inside will ask you if you want to Trade your abra for a mr.mime. Just agree. The higher your level of abra , the higher the mr.mime will be.
I hope this helps, and if it does please give a thumbs up so that I can post my cheat to get a mr.mime also.

You can find him after you get out to Pewer city, as if you was going home, you can use cut on a tree to go as if you was going in to get I'm the digglet's cave, and instead you will see a house pretty close, that ia the same house where you receive cut, so to get Mr. Mime, it is really best to already have gotten cut, I had gone once but forgot where it the Trade was, and was there just now since I got the Abra to trade it. If you already have cut you canake it this way, if not you will need to be star at Vermilion city, and go right to digget's cave, to go through the cave and once you get out you can see the house, get inside of it, and get Mo cut and trade too.
