Dehliop Four was home to the Dehliops, a warrior race much smaller than most of their neighbours. They developed a technology to make them bigger but with unfortunate side-effects. As a result the technology was banned and all the machines destroyed. One remaining machine (presumably smuggled off the planet), was onboard a crashed spacecraft which before being destroyed by the Eleventh Doctor was used by the Hope Institute of Science to super-size fruit and vegetables to meet the growing problems of world hunger.
