Pied Piper The Pied Piper was an energy entity originally from the Jeggorabax Cluster , a region known to house beings feeding on emotions . The Pied Piper manifested a need for fear in order to break loose from a piece of rock it was bound to , known as the Weserbergland meteorite . Biography . The entity crashed to Earth in the Weserbergland Mountains in Lower Saxony in 1283 , and by 1284 had broken loose from the meteorite by feeding on the local inhabitants ' fear of the plague . He acted benevolent to the people of Hamelin and rid them of their infestation . However , they refused to pay him and as his first major act , he used his powers to lure the children away in order to elicit fear from their parents ; thus he became known as the Pied Piper . ( TV : " The Day of the Clown " ) The Pied Piper took the children to his own realm , which included such wonders as toffee apple tree s , lemonade fountains and a barley sugar grove , but they soon tired of these and began longing for their parents . The First Doctor , John and Gillian arrived and decided to help free the children . They travelled to the Pied Piper ' s castle , where the Piper challenged the Doctor to pass three tests or become his prisoner . The Doctor used various technological tricks to pass the tests , then led the children back to Hamelin . ( COMIC : " Challenge of the Piper " ) Over the next seven hundred years , he continued to abduct children in order to create fear . One notable stint was an eight year period between 1932 and 1940 , in America , as " Odd Bob the Clown " . Among the kidnapped children were Louis Arbourne , Melissa Deaver , Barbara Knorr and 26 children of the Millhouse community . Odd Bob was also responsible for instilling coulrophobia in young Sarah Jane Smith as he saw her as a potential threat in the near future . In 2009 , he set up Spellman ' s Magical Museum of the Circus in London in order to steal children from the city . This was made possible by the fact that the Weserbergland meteorite was on loan to the nearby Pharos Institute . He managed to kidnap several children , among those were Tony Warner , David Finn , Jeremy Larsson and Tricia Chan . The now adult Sarah Jane Smith prevented him from stealing more children from Park Vale Comprehensive School , but he abducted Luke Smith and imprisoned him in his hall of mirrors . With the help of Rani Chandra and Clyde Langer , Sarah Jane overcame her fears , which weakened him to the point where she could force him back into a fragment of the Weserbergland meteorite . She then placed the fragment in an alien box from which nothing could escape . All the children that had disappeared within the previous weeks in Ealing reappeared when the Pied Piper was defeated . ( TV : " The Day of the Clown " ) Abilities . The Pied Piper was a very powerful entity . Its powers included teleportation , telekinesis , telepathy , shape shifting , limited reality - warping and mind control , although the victim needed to touch or be holding something for him to channel it into them , such as the balloons or tickets . The entity needed fear to power his abilities and keep himself in existence . He was greatly susceptible to laughter as it weakened his power , since he fed off fear . Shape shifting was one of his powers . The Pied Piper transformed his body , clothes and voice to new forms ; he only showed three forms in total to Sarah Jane but hinted he could have more . Unless he was trying to lure children into his trap to feed on their parents fear , the Pied Piper stayed as Elijah Spellman and ran " Spellman ' s Magical Museum of the Circus " .
