Oggy and the Cockroaches (1999)

S07E12 Bleached!

The roaches decide it's laundry day, but things take a turn when the washing machine starts overflowing, creating a sudsy mess all over the house. Just then, a rainstorm sweeps in and washes everything away, causing the house and its residents to reemerge—now in black and white. This twist serves as a fresh take on “Black & White.”
