Codename: Kids Next Door [TV]

A mysterious treehouse hidden from adults is the headquarters for five friends known as Kids Next Door. These 10-year-olds take on adults to get out of going to the dentist or summer camp by using “2×4 Technology.” They build and design elaborate contraptions using anything they can get their hands on: bubble gum, old wood, and spare tires. Each kid has a specialty and works with the team to win silly battles with adults.
