Duappy, a virtual pet kept alive the longest, has been stolen, and it is up to Fillmore and Ingrid to find X's pride and joy before a reporter comes to X to do a story on Duappy and before Duappy dies.

Mrs. Lawson's field trip to the Modern Contemporary Natural History, Art, Science and Miniature Museum takes a horrifying turn as someone draws a mustache on the priceless painting "The Lobster Man at Port". Fillmore, Ingrid, and O'Farrell work to find the culprit and save the painting, but the clock is ticking and everyone's a suspect.

Vampirita, a series of novels about an astronaut vampiress, has attracted a huge following at X—and none moreso than Torrey and Terri. The next installment of the series will be released in a fortnight, and until then, fans can audition to star in the next book. The girls start to build projects to win the auditions, but every time one is finished, it gets sabotaged. The main suspects are two members of a rival novel's fan club, however, the evidence seems to point to neither of them.
