Little Birdie is a small, white creature and the earliest form in Ridley's life cycle that has been observed by Samus. He was cloned from the DNA of the original Ridley. Samus first encounters this creature in Sector 1 (Biosphere) then again after she defeats the King Kihunter. After being attacked by the Mystery Creature in the Biosphere Test Area, Samus notices the shed skin of Little Birdie near a trail of green blood that leads to Lyle Smithsonian.
