Supa Nova

Nova and her older sister Cassi are being raised by parents who are scientists for a "boring" secret government agency, so when Nova is worried about the effects of plastic pollution on the planet, she springs into action. Heading to her scientific lair, she manages to create a creature who eats plastic, with the help of a discarded piece of Cassi's bubblegum. Chomp does a good job at eating and digesting plastic, but is a little TOO enthusiastic, and ends up eating kitchen cabinets and other items around the house. As Chomp continues his rampage despite Nova's best efforts, she decides to create a shrink-ray spray, since Chomp grows every time he ingests plastic. It's hard to catch him as he breaks out of his plastic box and hits the town, and his ever increasing size makes him hard to ignore. He ends up on the news when he ends up in the city, eating the plastic roads and interacting with rescue workers. Desperate, Nova calls on Cassi for help, even though the two fight more often than they work together. While Nova's parents aren't thrilled about the damage that Chomp has caused, they are glad to see her using her scientific skills for the betterment of the planet.
