Sing, dance and have fun with the music video for the song "Let's Make a Mistake", an anthem for 'The Paper Girls Show' and the maker generation. The song celebrates imperfection, and highlights the positive aspects of failure - while inspiring creative thinking to "help make the world a better place".
Caily asks Jax for help figuring out why her fish Fabio isn't feeling well. He encourages her to look at a sample of Fabio's fish tank water under a microscope, and Reese's research catches the culprit: pesky protozoa. Kami asks the girls for help with Dev, who is terrified that Parchment Pond is haunted by glowing ghosts, but a microscope reveals the truth.
Queen Frivol gets upset when she discovers that her beloved Shredder - Melvin - has been recycling stuff from her prized junk pile at Uncle Seymour's Fix-It Shop. Kami and Uncle Seymour ask Reese and Caily to hide Melvin in their world until the Queen calms down; Melvin makes mountains of shredded paper for Edie's Earth Day presentation.
After Edie accidentally records over a treasured family vacation video, Caily is determined to lock her out of her computer. In Confetti, Queen Frivol is trying to steal Dev's family's secret lemonade recipe to win a contest. Caily and Reese show Dev how to write the recipe in invisible ink, and in the process, put their finger on an idea for an Edie-proof computer lock.
Reese and Caily's robotics team can't agree on a design for their robot for an upcoming competition. In Confetti, Kami introduces them to her uncle, Professor Seymour, a talented inventor who created the first robot Shredder. His story gives the girls an idea for how they can compromise and design a bot that everyone's on board with.
Caily’s DIY fish tank sensor fails and floods her room, ruining Reese’s entry for the hottest fashion maker show in town. They travel to Confetti and, thanks to Kami, find inspiration in the perfect pleats of an origami fish. Reese and Caily the construct a fabulous light-up dress out of paper and LED’s that takes center stage at the show.
