Hobo 13 - S1.E35

When Zim’s constant requests to the Tallest get on their nerves, they attempt to remind him that he is an Invader, not a battle soldier, and that he doesn’t have the training to use the equipment he requested. In order for Zim to prove himself to them, they send him to Hobo 13, an elite training facility that only the best of soldiers stand a chance of completing. While the Tallest hope that Zim will die on the mission and be gone once and for all, they soon discover that Zim is much more cunning than they gave him credit for.
