Snubble cannot be caught in firered to get one trade one from emerald or colosseum.
On fire red you can not find snubull. But you can find snubull in Pokemon colleseum on gamecube.
You have to trade one from Emerald.
If you REALLY want a Snubull, you can go to the GTS (if you have Wi-Fi), and offer a legendary or a shiny for a Snubull. It'll get taken really quick depending on the Pokemon. But only do this if you really want one. Don't waste your good Pokemon.
Snubull usually comes as a swarm Pokemon, which you can check with Professor Oak and Mary's talk show on the Radio every day once you have obtained the National Pokedex and have defeated Red.
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
There is no Pokemon convention in firered.
Snubull are usually found in swarms. Otherwise, they are really rare. Swarm locations and the Pokemon type can be found by listening to Professor Oak's and Mary's talk show on the radio.
