Welcome to Tickle Town ( comic story ) Publisher ' s summary . The Doctor and Clara take a trip to Tickle Town , an amusement park , where Clara meets her cartoon hero , whilst the Time Lord uncovers the terrible secrets at the heart of Tickle Town after crossing paths with a desperate mother and daughter . Summary . Part 1 : Welcome to Tickle Town . Carstairs , crawling through a tunnel , begs his ally to slow down in fear of a movent - caused collapse . The other man , however , senses that tonight is the night they escape , adding that he would rather be dead than stuck in where they otherwise would be . The pair manages to pass the perimeter wall , but as they reach the surface , the Doodlebugs , a group of cartoonish - looking butterflies , sing a tune warning that escape is impossible . Meanwhile , the Eleventh Doctor and Clara arrive in Tickle Town , a far - future amusement park . Clara recognises a statue of supposed founder Tobias Tickle , whose cartoons entertained her as a child , but is displeased to see a large amount of extraordinarily obese residents . As the Doctor childishly enjoys the park ' s rides , Clara meets Hopalong Harry , an anthropomorphic frog whose show Clara ' s young self particularly enjoyed . After hearing that Clara is a newcomer , Harry quietly notes that it might be wise to simply " keep moseying along . " The Doodlebugs spot the TARDIS , throwing it into their garbage truck while singing another tune . Constable Claws , another cartoon character ( in fact a solid light hologram , as explained by the Doctor ) explains that leaving the TARDIS lying around is considered littering , a serious offence . However , the Doctor shakes up a drink bottle , exploding the drink on Constable Claws and allowing the Doctor to escape via a futuristic car . Constable Claws ' rodent assistant mentions that the Doctor arrived with Clara , whom he can lead the Constable to . A girl and her mother find the Doctor after he accidentally crashes into cartoon elephant Ellie Phunt , and , not recognising him , they realise he is a newcomer . Meanwhile , Constable Claws finds Clara and grabs her . . . At the Edu - Zone ' s Physics Plaza , a sparsely occupied location , Rupinda and Meera Kholi introduce themselves to the Doctor . They tell of the amusement park ' s wonderful opening day twenty years prior , which was interrupted as the sun went down . An energy wall had formed , imprisoning everyone at Tickle Town . Since then , the population became divided into three groups : lifers , who completely gave up hope of escape and , with the help of sedative - laced " munchies , " simply enjoy the amusement park without complaint ; visitors ( including the Kholis ) , who grow their own food and unsuccessfully attempt to escape ; and empties , who begin as visitors but are taken through a traumatising " special ride . " Constable Claws brings Clara to the aforementioned ride . She is subjected to a song ( accompanied with seemingly real visuals ) explaining the outside world ' s horrifying situation . Supposedly , war - born zombie armies menace humanity ; the forests have burned ; the lakes have all been eliminated ; and poisonous clouds fill the air : " . . . It ' s a red , dead world outside ! " Part 2 : The Hidden Heart . Hopalong Harry rushes into the room , having worked up the courage to do so after seeing Clara carted off . Meanwhile , the Doctor , still with the Kholis , notices the strangely large amount of Tannoy posts , all placed in geometric patterns . Using his sonic screwdriver , he discovers that these posts double as Transmat Pylons . He inverts the resistor cones of one to teleport , escaping the aptly named Bronto Brothers who are after them for tampering with the Tannoy post . Constable Claws is startled to find Hopalong Harry exiting with Clara , and forces them back where they came from by sending the Doodlebugs after them . The pair find and enter a small , circular trap door on the ground , and Constable Claws decides to bust it open . The Doctor and the Kholis have teleported outside of Tickle Town , specifically into a power conduit which contains the energy used to run Tickle Town . Harry and Clara , meanwhile , have fallen into another room , occupied by an extremely ancient Tobias Tickle . His blood having been replaced with preservative fluids and his breathing supported with machines , he was able to survive for over three hundred years . Impressed with Harry ' s ability to rise above his programming by saving Clara , he promises the frog a position as Tickle ' s successor . However , at this point , the Doctor , Meera and Rupinda enter the room , angry at Tickle for forcing so many innocent people to reside in Tickle Town for twenty years . Constable Claws , himself interested in what Tickle has to say for himself , agrees to a truce with the Doctor . At the end of the previous century , Tickle claims to have foreseen a final war which would eradicate mankind . He supposedly created the innocent , happy Tickle Town to save a group of humanity from this conflict . However , the Doctor , who is familiar with the era , explains that the aforementioned war was averted . Tickle runs the " ' world outside ' program " to prove him wrong , but he fails to scare either the people or the cartoons . Constable Claws , angry at Tickle for keeping him a prisoner of sorts as well , attacks and kills the weak , ancient man ; however , overexcited about his newfound freedom , he decides to kill the Doctor next . Harry reacts by attacking the Constable , disrupting both beings ' internal matrices beyond repair . The Doctor shuts off the amusement park ' s central holo - projector and repairs the transmat engines , opening Tickle Town ' s gates for the first time in twenty years . He and Clara depart in the TARDIS , the latter carrying a Hopalong Harry toy . . . Plot . " to be added " References . " to be added " Notes . " to be added " External links . " to be added "
