When they were 1, they were cursed by Putrid and Pouncer Popple to turn into werewolves every night and become evil, until a member of the Rodster family breaks the spell. When they were 3, they made magnetic friendship bracelets so that they remind them of their family. When they were 4, Jo and Jane Rodster's parents, Joanne and Stephen Rodster, were killed by Putrid and Pouncer Popple in the Chipotleville Massacre of 2012. They were forced to go to Miami, Florida to be safe from harm. At a dumpster, they found 10 Popples; Clumsy, Eccentric, Muscular, Floral, Quirky, Cotton, Rocketeer, Candy, Surveillance and Hyperactive. They are taken to be Jo and Jane Rodster's new friends and they are given the power to turn into Popples themselves. In 2014, they were taken to the O'Neill Orphanage Center by Zachary and Katherine O'Neill. In January 20, 2016, the spell was broken when Jo and Jane's cousins, Nolan and Laura, kissed them on the cheeks.
On February 26, they were adopted by Halley and Daryl Wagner along with Emilia Caprice. On July 19, Jo and Jane found out that their mother had survived the massacre, secretly adopted Bronson and Kathryn, and is living in the Rodster Mansion to work on reconstructing Chipotleville.
Jo is a very hyperactive girl. She is also very silly, quite zany, and really comical. She is also a little bit mischievous, and sort of troublesome, but is always very sweet and graceful. Jo loves to paint many kinds of flowers, bunnies, and candy. She also loves to listen to many types of music genres, but the ones she really likes are Pop, Classical, and Electro-Pop. She loves to have fun with her friends, Stephanie Charikan, Reena Raccoon, and Katherine Koala. She loves balloons and jokes because they always cheer her up whenever she feels sad.
Jane is very intelligent, quite intuitive, and really quick-witted. She is also pretty curious, quite interested about researching and very eager to know more about robotics. She is also pretty quirky like Jo, a little bit zany, and really eccentric. Jane herself loves everything about forensics and wants to know more about it. She loves to do diagnostics and talking about logic. She loves reading detective fiction like Sherlock Holmes and much more. What they both have in common is that they really love the TV series, The X-Files. They also like, to tell the truth, rather than lying all the time. They also like to pretend that they are detectives with their own magnifying glasses.
