Johnny "borrows" his sisters' worker drones to build the ultimate treehouse to impress Sissy, but ultimately ends up failing.

When Johnny breaks his foot in a dangerous stunt, which Hugh and Lila ground him for, his sisters step up to create a robotic one for him.

Johnny disagrees to help the girls test experiments so they create a special doll that can control Johnny but Johnny seeks revenge and creates special dolls that can control the girls.
