The “Terrible Bacteria Boys” were a horde of sentient, more-or-less-anthropomorphic bacteria inside a dream Scrooge McDuck once had.
Description[]
Inside a dream Scrooge McDuck experienced in 1983, wherein which he and his nephews had used Gyro Gearloose's Shrinking Machine to visit the microcosm that existed inside a single cell of a single leaf of an oak tree, he witnessed one of the many confrontations between the Chloroplasts and the “Terrible Bacteria Boys” who tried to infect the building blocks of the cell, and had to be fought back. Appearing as something akin to an army of demons from a Hieronymus Bosch painting, the Bacteria were resilient and brutish, but rather unintelligent.
Behind the scenes[]
The Bacteria Boys serve as antagonists in the 1983 story Plantastic Voyage.
