Zim finally finishes one of his self proclaimed brilliant inventions, a space-time-object-transfer device, in which he plans to send a giant robot into the past in order to put an end to Dib once and for all. However, when the robot isn’t compatible with the temporal field, he throws a rubber pig into the vortex instead, which turns out to be compatible and it causes Dib to crash his tricycle in the past . Zim decides to send many more rubber pigs into Dib’s past, which ultimately affect him in the future; though when Zim overdoes himself, he discovers that history isn’t something that should be messed with.
