Foamasi The Foamasi were a race of stocky , reptilian humanoid s . Biology . Foamasi were stocky humanoid s with shiny green skin , three claws on each hand and eyes that could move independently . Foamasi spoke in a clicking language and were physically incapable of speaking human languages . ( TV : " The Leisure Hive " ) This language directly stimulated the visual cortex of the brain , meaning Foamasi effectively saw their language . ( PROSE : " Sleepy " ) Foamasi also had the highest radiation resistance in the Galaxy and could survive in heavily irradiated areas . ( TV : " The Leisure Hive " ) Foamasi had hollow bones with double joints every few centimetres , a high liquid content , small organs and a retractable tail . These traits allowed the Foamasi to compress themselves into very small spaces , such as humanoid skin suit s . The Foamasi had green blood . ( PROSE : " Placebo Effect " ) Culture . In the 23rd century the Foamasi were controlled by the government and there were no private organisations . This government didn ' t take kindly to any criminal activities by Foamasi and sent special agents to stop them . ( TV : " The Leisure Hive " ) Later , during the 30th century , the Foamasi society became corrupted , and the various criminal Lodges started to gain power . ( PROSE : " Placebo Effect " ) Some of the criminal organisations that had sprung up were the West Lodge , the Dark Peaks Lodge , the Twin Suns Lodge and the South Lodge . They relied on gambling , drug - dealing and prostitution for income . They could be told apart by their methods and their voices , since each Lodge generally used different sources for their communicators . ( PROSE : " Placebo Effect " ) Foamasi were known to produce brandy . ( PROSE : " Prime Time " ) Technology . The Foamasi had a variety of technological devices . The agents of the various Lodges made use of skin suit s , which they used to impersonate Earth officials . They also had communicators that could translate their native speech , which they kept in their mouths . ( TV : " The Leisure Hive " , PROSE : " Placebo Effect " ) The Foamasi agents also used cocoon grenade s to wrap up criminals . ( TV : " The Leisure Hive " ) History . In 2250 , the Foamasi were involved in a 20 minute war with the Argolin , during which they attacked Argolis with 20 , 000 missiles , leading to the planet becoming sterile and highly radioactive . They later attempted to buy the planet , since they could survive the conditions on the surface . The private West Lodge attempted the same thing illegally . A group of Foamasi arrived on Argolis and arrested members of the West Lodge trying to make the deal . During this period the Foamasi and the Argolins dispelled their grudges and became friendly towards each other . ( TV : " The Leisure Hive " ) In the 26th century , Foamasi lived in Mega City , Megerra . ( PROSE : " Shakedown " , PROSE : " Mean Streets " ) In the 30th century , the Foamasi were united in a war with an opposing force . This would be one of the last organised acts of the Foamasi , and soon afterwards the Foamasi would become less focused in their goals . ( PROSE : " Placebo Effect " ) In the late 30th century , the Foamasi were members of the Earth Empire . ( PROSE : " Original Sin " ) In the 38th century , the Dark Peaks Lodge was formed in an attempt to create a better organised force in the galaxy . In 3999 , the Dark Peaks Lodge started to try to take over other Foamasi ' s activities . They started by taking over Carrington Corp . Using these new connections , they heard rumours of a drug being produced on Micawber ' s World . They decided to investigate , even though they weren ' t allowed on the planet . After reaching Micawber ' s World , they learnt of the disappearances underneath Micawber ' s World caused by the Wirrn . They manipulated the people there to investigate the matter for them . When the Twin Suns Lodge also sent Typtpwtyp to investigate , the Dark Peaks Lodge murdered him . The murder of Typtpwtyp got the Eighth Doctor involved and soon he learned of the Dark Peak ' s involvement . When the Foamasi ambassador , Green Fingers , learned the truth about the Dark Peaks , he had the leader killed and all the other agents hunted down . ( PROSE : " Placebo Effect " ) The Foamasi still existed circa 2000000 . Shortly before Ricosta was attacked by Sperovore s , several Foamasi landed on the planet . The Mayor of Ricosta ' s secretary Valla informed them that they needed a visa before they could make planet - fall . ( AUDIO : " A Life of Crime " )
