Dark Harvest

"That one's got head pigeons, the other one is just annoying! Fix it!"

- Ms. Bitters

Plot Summary
One day at Skool, Dib decides to scan Zim with his brand-new X-Scope. What he finds is incredible: none of Zim's organs bear any resemblance to those ofhumans. Later in Ms. Bitters' classroom, when Zim gets Head Pigeons, Dib realizes that when the nurse examines him, she will quickly discover his alien nature. However, when Dib blurts this to Zim, the Irkendecides that, in order to appear more human, he must obtain human organs. Meanwhile, Dib decides to get to the nurse's office to ensure that things turn out the way he hoped; he does so by jamming a pencil up his nose, and claiming to Ms. Bitters that it has lodged itself in his brain. She acquiesces, but forces him to take the auxiliary Hall Pass - a radiator.

However, when Dib finally reaches the nurse's office, Zim is nowhere in sight. He asks the secretary if she saw a green-skinned child enter the office, and she points toward the hall monitor, who is sitting in one of the chairs doubled up in pain and mumbling "the cooing..." over and over again. Dib quickly uses his X-Scope on the monitor, and discovers that one of his organs has been replaced with Zim's Hall Pass.

Dib realizes that Zim now fat in the cafeteria but a scene of him getting fat is not shown has started going around the Skool, ambushing unsuspecting skoolchildren and using a device in his PAK to steal their organs and replace them with various objects. One student that doesn't seem to care is Gaz, who had one of her organs replaced with her Game Slave; as a result, glowing lights appear on her midsection. Dib quickly teams up with Torque Smackey, the only other kid who has not been caught, and tries to protect him from Zim's gruesome harvest. He eventually fails, however, as he turns away for one second, and Torque is gone. Dib realises that he is the only one left, and a mysterious cooing sound is growing ever nearer...

Zim pursues Dib throughout the Skool, into its very depths. Unfortunately, Zim finally corners him, and replaced one of his organs with a mooing sound can.

Ultimately, Zim's plan is a success: He manages to fool the Skool nurse, who proclaims him to be "perfectly healthy... with such plentiful organs." Dib, however, isn't so lucky: the organ replacement caused him to produce a mooing sound whenever he exhales, and this causes the nurse to scream that he is not human. The incident makes the front page in newspapers everywhere, with the headline proclaiming: "Hideous Mooing Cyborg Boy Found!"
