The Sulfur Dragon was released on March 1, 2013. 

Rarity: Common
Colors: Black, Orange

The sulfur dragon has 2 different color forms. The orange form (or "sick" / "infected" form) is obtained when another user (or yourself) with an unfrozen orange hatchling clicks your sulfur eggs or hatchlings (not adults). However, the rate of successful infection varies as it is harder to infect when there are many orange sulfurs already in existence. The sickness can be identified in the description of the egg, or color of the hatchling.

This egg smells like sulfur. (Black) 
This egg smells like sulfur. It seems sickly. You worry about it.
Hatchling icon Hatchling
With a creak and a crack, the egg pops open! This newborn dragon looks more like a hungry piece of lard rather than a dragon-- it can't even roll over.
Hatchling s2 icon Mature Hatchling
This baby dragon looks more like a hungry piece of lard rather than a dragon-- it can't even roll over. It's growing stronger every day and has now developed a very grumpy attitude towards everything.
Adult icon Adult
Sulfur Dragons are one of the laziest dragons ever to be discovered. They come equipped with a bad attitude and a lot of extra fat, usually acquired by eating a lot and never doing anything to lose those pounds. Due to their weight they are unable to fly, so they just use their wings to fan out their stench. Because of this mix of negative attributes, nearly every breed of dragon tends to stay away from Sulfurs.
