Oggy is trying a new, super-strong detergent. The cockroaches decide to fill the washing machine to the brim with it as Oggy exits the laundry room. This causes the washing machine to over-flow and cover Oggy's house with pink foam. When a rain cloud washed it off, the house (and the garden) has lost all its colour. This has quite a depressive effect on both Oggy and the cockroaches.
