sentences:  In a desperate act to get Zim as far away as possible and ensure he would not ruin things the second time around, The Tallest send Zim on a fake "secret mission" to a "mystery planet" located on the outskirts of their known universe which they do not think even exists, in order to keep him occupied and away from the real invasion.Zim is joined in his mission by GIR (Rosearik Rikki Simons), an ineffective and erratic Standard Issue Information Retrieval (SIR) unit which was hastily made out of spare parts found in a trash can.After a six month long trip across the universe, Zim finally arrives at this "mystery planet" which not only really does exist, but also coincidentally happens to be a dark and satirical version of Earth.
