Kim Possible is an early 2000s American action cartoon series created by Bob Schooley and Mark McCorkle for the Disney Channel. It centers around a teenage girl who, along with her clumsy sidekick friend and his pet naked mole rat, saves the world from mad scientist Dr. Drakken and other such supervillains.
Dr. Drakken steals a top secret experimental substance known as super-concentrated self-replicating synthoplasma. It's basically a slime monster, which gets out and starts eating everything in sight, growing as it does. It even would have eaten Kim if she wasn't saved last minute by her mother.
