Eden (planet)
From Tardis Wiki, the free Doctor Who reference
Eden was a dark, hostile jungle planet. It was the native planet of the Mandrels. Eden was also populated by a glowing insect with a bite that stunned. Even also had carnivorous, people-eating plants which snagged its prey with vines and then drew the prey into its maw. Biting through a root would cause what appears to be green blood to squirt out and make it let go of its prey. A section of the plant was captured by Tryst in his Continuous Event Transmuter. Eden also had an orange atmosphere and was constantly bathed in orange twilight (possibly due to an orange sun or suns). (TV: Nightmare of Eden)
