The Fiery Dwarf Bulblax is a fiery member of the Breadbug Family featured in Hey! Pikmin. Like most of the other "Dwarf" version of the Bulborbs, it evolved to mimic the Fiery Bulblax and like it, it is able to constantly produce fire from its back.
The Fiery Dwarf Bulblax leave a fire trail behind it while walking, which mean that to defeat it or even toget close to it, Red Pikmin are needed. Captain Olimar must also throw them on its back to kill it, the Fiery Dwarf Bulblax is an agressive creature and will actively try to eat or kill the Pikmin.

"This creature's back is perpetually burning, so it leaves a trail of fire wherever it goes. I wonder how those bulging eyes keep from getting cooked sunny-side up. Now that's a matter worth researching."
