EngiNerds

The book follows a group of super-smart friends, known as the EngiNerds, who have been close since kindergarten. Ken, one of the EngiNerds, is initially excited when his best friend Dan secretly sends robots to each member of the group. The robots, designed to perform tasks like cleaning and walking the dog, seem like a dream come true. However, things take a turn when Dan's robot, Greeeg, begins consuming food excessively and transforms into a destructive 'butt-blasting bot.' As the other robots also 'come alive,' the EngiNerds must band together to prevent disaster and save the planet.
