After closing hours, in a shopping mall, Dawn, a cleaner, is running for her life. She is chased by three creatures that look like The Doctor, Amy Pond and Rory Williams, but with green skin and crazed red eyes. Heading for the panic room in Bleachers Pharmacy, Dawn is rescued by the real The Doctor, Amy Pond and Rory Williams. The PoriPhlums are drawn to the alternative fluid source and start to gorge. "They slurp until they blurp!" until, the sugar, reacting with the yeast bacteria, turns them into giant cake shapes.
