Wrong Side of the Bed is the 13th episode of Season 1, and was remade as the 31st episode for Season 6 under the title Bad Luck Day. Oggy becomes afraid of bad luck when he finds out that today is Friday the 13th.
In the morning, an alarm clock wakes Oggy up from his sleep, as he tried to stop the alarm, Dee Dee kicks the clock and switches with a cactus which stings him hard while the cockroaches escape with laughter. Oggy checks his calendar, he finds out in shock that today is Friday the 13th, a day of bad luck. And obviously the cockroaches are taking full advantage of Oggy’s superstition, like making the mirror cracked, and sabotaging Oggy during his tarot fortune.
After that, Oggy takes every lucky item he has, but when he tried to look for his lucky horseshoe, the cockroaches switched it with a magnet painted as a horseshoe, causing every metal object in the house coming after him to the toilet, and was then flushed down the drain by Joey and Marky. As Oggy found out the horseshoe he has was a magnet, he throws it away without knowing it came back like a boomerang, along with electronic appliances attracted. Crashed into the storage under the stairs, Oggy was spilled with black paint, and the cockroaches laughed at him.
But the laughter grew silent as they see Oggy, whose now a black cat after being spilled by paint, Marky shows Joey and Dee Dee a picture, shocking both that a black cat can cause bad luck just by passing them. This causes nightmares for Joey, Marky, and Dee Dee, as they ran away in fear. Oggy, coming out of the storage, saw that he became a black cat, give a grin and walks after them, just as the toilet came falling. As the cockroaches run for their lives, the kitchen appliances exploded and the floor cracked just as black Oggy went by. In the living room, the cockroaches hide under the couch, and laughed as black Oggy went passed them, but were shocked as random things start falling, from a closet, to a bus, then a ship, to falling UFOs, and the Moon crashing to the Earth's surface.
