The Kramden Quads are Emma, Jules, George and Lyle Kramden. They're recurring quadruplets on Nicky, Ricky, Dicky & Dawn. The Harper Quads consider the Kramdens to be their biggest rivals even though the Kramdens adore the Harpers.
The Kramdens replace Nicky, Ricky, Dicky and Dawn from the tires commercial after the Harper quads complain about doing the same lame commercials every time. This makes the Harper Quads insecure not only because they're being replaced but also because the Kramdens seem to be more harmonious than the Harpers. While the Harper Quads argue about everything, the Kramdens do everything in harmony.
One of the Kramdens suggests that the Harpers don't even act like a real quad and they don't look alike. So, Dawn and the boys decide to look for evidence to prove that the Kramdens are the ones who are not real quads. They start spying on the Kramdens and collecting their DNA samples.
The Kramdens are disappointed by the Harper Quads since they used to consider them as their idols.
The Kramden quads sign up for the annual Bobsled race, making the Harper quads nervous. In the previous years, the Harper quads were the only ones to signup and still lost because one of them would mess up and get them qualified. Dawn says the Kramdens want to steal their race just like they stole their tire commercial in Odd Quad Out.
The Kramdens tell the Harpers to get ready to lose! Dawn tells them that they could beat the Kramdens in their sleep but Emma corrects her that it should be "in their dreams." The rest of the Kramdens laugh at the Harpers in union and leave. With Kramdens in the picture, the Harpers are afraid of having a real competition and losing. Dawn gets even more concerned when she realizes that the Kramdens do everything in sync unless she and her brothers who can barely agree on something simple. Ricky is impressed by the Kramdens' snappy comebacks. The Kramdens make the Harper quads so nervous that they can't even sleep the night before the competition. The Kramdens, on the other hand have a good night sleep.
During the competition, the Harpers fall asleep in the sled, and therefore don't do anything to get them disqualified. They defeat the Kramdens - in their sleep, literally.
