Drizzle Viper ( Nether Update Mob Idea )

The Drizzle Viper would be a long snake like creature, that would have a spiny back and a pointed tail. It would swim around in lava and wait for players to get to close to the edge of the lava pool, and lash out and bite them. Once the player is bitten, you would get an effect called Burn, very similar to poison, but deals more damage. I feel like it could drop and item, but it would be hard to get it if the creature lives in lava ( Fire Resistant Items ? ) Hope this idea is at least noted down :)
