I got omega squad teemo in a mystery skin. Is he fun? Also what roles can he play besides top?
Oh yeah, a good Teemo game can be great fun (for you, not for the enemies :p). Top is his standard lane, but you can take him to the mid lane, bot lane and jungle. Anywhere you want actually. The efficiency of certain positions may be questioned, but if you can adapt to the situation and learn how to effectively use your shrooms, invis and get a feel for the right timing to join a fight he can actually be played anywhere.
I think jungle Teemo is a pretty fun approach and as long as you get a good leash and you're not getting heavily invaded you'll be fine for the jungling part. The damage he can put out with red + red smite + toxic shot is great and you can catch quite a few AA reliant champs by surprise if you use your Q right.
Your shrooms also offer you superior map control and I've seen teams getting 4 red trinkets just to clear the shrooms, so they would end up without any wards on the map.^^
This is the guide I used for getting into it, watch the newest video so you can see how to clear your jungle safely and try to stay flexible in how you use this little guy.

he is a great carry for low elo where noone knows what a pink ward is
I gotta admit some of those games were pretty low Elo due to me playing with lots of Bronze premades, but even when they used pink wards and tons of red trinkets I did quite well. The guy I got this build etc. from just got Master Tier and people had no idea what to do since they just never play against him. And he's just tons of fun^^
