Biography

Creation

The Robo-Boogers are briefly seen at the end of Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy Part 1: The Night of the Nasty Nostril Nuggets. They are created by the remains of the Bionic Booger Boy, after Melvin is separated from the boogers and robotic body. They slid off of some walls and smashed the Combine-O-Tron. They then chase away the protagonists as the story ends.

Reign of Terror

The Robo-Boogers were beaten up and shot into space by Sulu the Bionic Hamster, who heard the screams of terror caused by the protagonists. The three are launched into space, but they later stowaway on a spaceship to get back to Earth, and attack the space station in the process. Later, George, Harold and Captain Underpants(who has lost his powers), have been pursued by the Robo-Boogers.

Demise

George, Harold and Captain Underpants learn that the Robo-Boogers' weakness is vitamin C when Carl falls apart after eating an orange. Before Trixie and Frankenbooger could eat George and Harold, Captain Underpants annoys them by dancing atop a toilet, and the remaining Robo-Boogers go after him. They the toilet seat, which has oranges under it, leading to orange juice splashing on them, killing the Robo-Boogers for good.
