The Thrunn were large, mult-tentacled blobs with green or yellow skin and one large eye on a stalk. Two Thrunn once crashed in the desert. Coming to the attention of movie director/producer Larry Haxton, one was held captive onboard their spaceship while the other was forced to star in his film The Blob from Beyond. The Thrunn escaped with the help of the Tenth Doctor and Betty and returned home. (COMIC: Creature Feature)
