Super Metroid Randomizer [#06] / Ridley /SNES

THE METROID MENACE

Emergency! Emergency! Return immediately to the Space Science Academy!
When Samus made her way to the research facility, she found the building in ruins and the Metroid larva was nowhere to be found. Out from the darkness came a group of Zebesian space pirates and their leader, Ridley, who had the Metroid larva in tow. The pirates fled to a rebuilt planet Zebes and Samus followed them, resolving to finish them off and save the hatching!
