Super Mario World/Enemies/Blargg

Blargg is a bizarre dragon-like creature that dwells in lava. They usually appear in levels where Mario has to cross large lava expanses on skull rafts. Blargg usually announces his presence when his large white eyes peek out of the lava (some say the eyes look like a piranha plant). Blargg will make a lunge toward Mario, which can easily be avoided with a jump. If Mario is on Yoshi, Blargg is no threat because Yoshi can step over him, and if timed properly Yoshi can turn backward and swallow Blargg whole before he sinks into the lava again.
