Nobita follows him there after he has gone for a long time, and discovers a strange bowling ball-like orb which starts blinking with a pulsating light, and summons what looks like a giant robot´s foot. After sledding down the hill on it and having it crash into his room through the Anywhere Door, the bowling ball follows him home through the door and another robot piece falls into his backyard.
