Bubblewrap Monster

Bubblewrap Monsters are creatures that originate from the Force Galaxy and terrorised spacers and colonists for centuries. The creatures can survive in space, and they spread their seed through the empty blackness of space in the hope that they will latch onto starships. Dozens of League ships have been infected this way. When the creatures get inside the ship they attack the crew and mutate them into six-foot tall green bubblewrap creatures who devour everyone else on the ship.

The problem got so bad that the League officials decided to instigate a plan to cleanse all ships that were infected, ordering all crews to abandon their ships at the first sign of infection and self-destructing the ships to prevent the spread of the seed.
