Krynoid planet of origin

The "planet of origin" of the Krynoids was located in the Mutter's Spiral. The Fourth Doctor theorised that it was possibly very turbulent from time to time, and that internal explosions could cause surface matter to go shooting into space, launching Krynoid seed pods into the galaxy. (TV: The Seeds of Doom) He also considered that the cold of Antarctica could be considered "glorious summer" on the Krynoid planet. (PROSE: Doctor Who and the Seeds of Doom)

Eve Black hallucinated about the possible Krynoid homeworld, and watched a creature like a giant hummingbird get eaten by a plant. (AUDIO: The Root of All Evil)
