Sulfur Fields is a minor location that appears in "Prehibernation Week" and the comic Grandma's Cookies. It is located presumably in Bikini Bottom and is a place full of sulfuric volcanoes.



Sulfur Fields is a field of small dark volcanoes that shoot out sulfur. The surface is dark grayish-blue and the sky is yellow-orange due to the sulfur being released into the air. There are also tiny patches of red coral and purple clams placed around the fields.
