Puffer (Metroid)

Puffers are gasbag-like organisms native to the Magmoor Caverns on Tallon IV. Puffers are dangerous creatures, their fragile bodies filled with lethal Meta-Viprium Gas, and they explode at the slightest touch. The gas they leave behind is just as lethal as the explosion itself.

Puffers are often employed as watchdogs by the Space Pirates on Tallon. A cybernetically-enhanced varient, the Preed, was also used on Aether.
