A creature known to the ringleaders on the BOTTLE SHIP as "Little Birdie" is a small organism seen in Metroid: Other M and is the larval stage of Ridley's life cycle. It was genetically cloned from DNA found on Samus' armor prior to the game's events. Not knowing it was spawned by Ridley's DNA, the scientists thought it lacked potential as a bioweapon, and instead began treating it as their pet, giving it its nickname. Some time later it was found playing dead in its cage and escaped after it brutally murdered the unfortunate scientist who discovered it.
