Benjix

The Benjix were small, green, one-eyed, highly flexible, six-tentacled creatures led by a Prime Benjix. They were known to invade planets using a Supermassive Matter Transporter (an industrial teleporter). An invasion of Earth, where they were distributed across the world hidden inside ‘food’ canisters, was foiled by the Tenth Doctor and Heather. The Doctor sabotaged the machine at TRASH INC’s 'Convert-o-Matic' factory by reversing the polarity of the transmit beam and sending them all back home with all the household rubbish before destroying the machine.
