Protoplasmica
From Starsonata Wiki
A special "hidden" galaxy, Protoplasmica is filled with hostile Goblins, and later Space Blue Betas. Watch out! Doc Goblin is lurking inside, waiting to destroy you with his unique Giant Goblin! Also, there are rumors that the Beta Monster reigns supreme deep inside...
2 interior levels require you to kill 2 adonis, and then argonaut drones.
