Space Dandy is back, baby! But as Dandy himself laments in the middle of this particularly chaotic episode, they “came back too much.” After trying to pass a cow off as an alien, Scarlett gives them a stern life counseling session, suggesting they may not be cut out for alien hunting, being the worst such hunters she’s ever seen.
As they ponder a future in space trucking, Dandy pulls at a stray hair on his head, it gets longer and longer until it envelops him, Meow and QT and zaps them into another dimension, where there is another set of Dandy, Meow, and QT (and Honey), only this set is much better at their jobs. They notice another stray hair, tug at it, and the process repeats.
They’re not stray hairs, but cosmic strings, and continually tugging at them zaps the crew from one alternate universe to another, in all of which some form of Dandy & Crew exist. Those forms get more and more bizarre until we end up with a scary Meow who simply stands around grinning and holding a helmet he never wears, QT as an old codger who thinks he’s a robot, and a gloomy Dandy who just wants to die, having clearly been around the other two for far too long.
With all the alternate Dandy crews springing up in one universe, not only does the Aloha Oe get overstuffed with people, but the universe itself starts to become full of contradictory information, to the point where even the normally unflappable narrator begins bickering with other narrators over what exactly is going on in the episode. If this goes on it can’t end well.
So the Dandys and their crews come together and decide to light the cosmic strings like fuses. When that happens, a big explosion occurs and the universe is seemingly back to normal, until it’s dropped on us that Gloomy Dandy and his two insufferably strange companions are the new cast moving forward. The show is just joking, but in the end, Scarlett was wrong about the Dandy, Meow, and QT she knew being the worst. There’s always worse.
