Ice Beam is a 90 power Ice-type move. It has a 10% chance of freezing the opposing Pokemon.
All you have to do is train your Pokemon or have a Pokemon with a good ice move
You can get it at Seafoam Islands or buy it with 10,000 Coins at the Goldenrod Game Corner.
you will find it on the ground but there is an ice puzzle to get it.
in the game corner
go to goldeen rod city and go in the big building andgo to the six floor
Every ice-type pokemon can learn this move (i think) Spheal, Snorunt, Altaria, Articuno, etc..
you can only get it from the move tutor in Blackthron City

You can find TM13 Ice Beam in the Seafoam Islands but can also find it in Goldenrod city. Use fly to get there; or if you can walk fair enough. Go to the Game corner. To buy ice beam you need at least 10000 coins. These are the only ways to get it in this game. Hope I helped!
