Screaming Jungle

The Screaming Jungle was a forest on Marinus.

The forest was biologically altered by Darrius in an experiment on speeding up the growth process of flora. The experiments made the flora move. It also seemed to have been made sentient. The flora could kill individuals by constriction. It was also strong, capable of breaking down walls. The flora emitted a loud screaming noise. (TV: The Keys of Marinus)
