Randy O'Rourke wants the robot he built to be as "Super Colossal" as those at Future World, an amusement park where robots do all the work. Brain doesn't disappoint him. He does Randy's homework and chores--plus some things he wasn't programmed to do. His red heart glows in response to compliments. He blinks when touched. He uses "mind talk" to communicate with Randy. However, some of Brain's unprogrammed actions are less endearing. From minor glitch to major, the robot presents a series of escalating problems. He's out of control, but Brain is almost human and Randy loves the big pest.
