you go to a secret house in the safari zone in fuschia city and a guy will give it to you saying its a prize.
you can find venonat in safari island which is where you get the hm surf
In the safari zone at fuchsia city.
The HM's that are in leafgreen are: Cut, Fly, Surf, Strength, Flash, Rock Smash, Waterfall.
HM03 is surf
Use the HM Surf to surf southward from the rock tunnel area soon you will find a building this is the power plant inside you can find zapdos.
Articuno is in Seafoam Islands you need the HM Strength to get to it though and the HM Surf also you need the 4th and 5th badge.
if its the hm surf, which i think it is, its in the saffari zone in the secret house, an old lady will give it to you
It's a hack (I think) of FireRed or LeafGreen. So, it must be in the Safiri Zone! In the Back is where you can find the guy who gives you the HM Surf!
Surf is a HM so you can teach it to multiple pokemon.
Go to the Safari Zone , pass it. If you see a house , well your in luck , because the person will trade the golden Teeth for the HM Surf!
You can find it in the Power Plant next to cerulean city. you need the hm surf to get there and you can also find other items + zapdos :)
