Comic Story
But during a comic taking place after the movie, he has not only survived, but also reformed helping out Olivia. When Olivia heard about the Sideshow Sea Beast, she called him and Toby and head out for the carnival. He told Olivia that the beast is the talk of the show and that he used to work at a carnival. Fidget even showed Olivia how some of the tricks are done. Once he showed her the attraction, the monster got angry and held Fidget captive. Olivia saved his skin by carrying a chum bucket, which is the beast's dinner. After the beast threw Fidget, Olivia hoped Fidget remembered that he can fly(how he got to fly again was unknown). Once the beast went back to the ocean, Olivia and Fidget celebrated with caramal apples.
