Melvin first attempts to combine himself with a robot, so he will intimidate George and Harold. However, he sneezes at the last second, due to being allergic to his cat Dandrella and he, the robot, and his snot are combined, resulting in the birth of the Bionic Booger Boy.


Melvin entering the room.

The following day, Melvin goes to school, when he opens the door everyone is in shock. As his hand leaves the door knob, globs of snot stick to it, Melvin then calls everyone immature. He then tries to sit in his seat as a puddle of snot surrounds him, he then explains how it happened to George and Harold.

Autumn Starts and the Cold and Flu comes with it, unfortunately Melvin catches it and snot spews everywhere, covering Ms. Ribble in boogers. The next day she is gone and Mr. Krupp takes over as substitute, not unlike Book 5.

Later, Melvin freaks out on a trip to a tissue factory, and when he is offered a pack, he grows gigantic and destroys the factory. He then tries to eat George and Harold, but Sulu beats him up. Later, Melvin's parents appear and reverse the mess, seemingly restoring their son. However, Melvin and Mr. Krupp have swapped bodies, and the Combine-O-Tron 2000 is then destroyed by the slowly forming Robo Boogers.
