Bugs narrates that strange carrots have traveled from outer space to Earth. He wakes up in his rabbit hole and remarks that he is late for work. His "work" consists of performing routines of outsmarting Elmer Fudd, Yosemite Sam, and Daffy Duck. During the first routine, there is a strange pile of glowing carrots in the background, but Bugs ignores them.
Taking a plane to the Wild West, Bugs goes through the old "I dare you to step across this line" gag with Sam. After Sam falls off the cliff and makes his way back up, he sees a pile of strange carrots along the cactus.
Bugs then takes a "Grey Hare" bus to meet with Daffy. They perform the "Rabbit Season, Duck Season" routine and hunters shoot Daffy. Again the carrots appear, but this time they are shown attacking Daffy as Bugs leaves for home.
The next day, Bugs wakes up and returns to "work", but Elmer looks and acts like a "pale stereotype" of his former self. Elmer appears poorly-drawn with choppy animation and a voice like a broken record. When he offers Bugs a carrot, Bugs leaves to find Sam, hoping that Sam wouldn't disappoint him.
Much to Bugs' chagrin, Sam also has also fallen victim to the carrots. Bugs finds the pale stereotype version of Sam, who wears a smiley face sticker on his shirt and forever says he doesn't want to hurt him (while moving like a character in a poorly-animated 1960s television cartoon), and walks off the cliff himself. When the fake Sam offers Bugs a carrot, Bugs then leaves to find Daffy.
Daffy, who has also fallen victim to the carrots, now flickers in and out of frame, and none of his body parts are well-attached. (At one point, his mouth is done Clutch Cargo-style!) He is also strangely friendly to Bugs, apologizing for their feud over the years through a human mouth attached to his beak. After Daffy gets shot by the hunters yet again, he returns, riddled with holes, and offers Bugs a carrot. This time Bugs accepts the carrot.
Bugs tries to figure out why the others appear so different. The carrot produces a pale stereotype of Bugs. The impostor attempts to kill the real Bugs with an axe and Bugs runs off screaming, but stops to remark "You know something, folks? This is the scariest part of the picture.", only to continue screaming again as it irises out for the first time.
The Looney Tunes end theme plays, but Bugs interrupts, claiming he must get to the bottom of the mystery. He finds tags on Elmer, Sam, and Daffy indicating that the impostors were made on the planet Nudnik, and realizes he must launch them into space to get the original Tunes back. He collects the now malfunctioning "pods" into a sack marked "pale stereotypes". He fires them into space, in a sequence with literal-minded depictions of the Milky Way and the Dog Star. Finally, a mouth materializes in a black hole and swallows the imposters. The next day, Bugs wakes up and outwits the real Elmer, Sam, and Daffy who have all come back.
In the post-credits scene, an impostor Porky Pig wearing pants pops out of the Looney Tunes drum, trying to utter the line "That's All Folks!" in a creepy, distorted fashion. Bugs then comes in and throws out the impostor, and then drags in the real Porky Pig and places him inside the drum. Bugs walks off as Porky chuckles and then says his signature line.

- It was first released in the 1992 television special Bugs Bunny's Creature Features, and never received an official theatrical release.
- It is a parody of Invasion of the Body Snatchers.
- The short was aired as a stand-alone on Nickelodeon, and then on Cartoon Network.
- An edited version of the cartoon appears in the Space Jam 2-Disc Special Edition DVD as a special feature. Yosemite Sam originally appeared in the cartoon, but was taken out by Warner Bros. due to "time allotment." Sam can still be heard in the edited version, when all of the Looney Tunes' "pods" are about to be launched into space. The uncut version of this cartoon is available on both The Essential Bugs Bunny and Looney Tunes: Parodies Collection DVD releases.
- Each of these "pale stereotypes" of Bugs Bunny, Daffy Duck, Elmer Fudd and Yosemite Sam have the tendency to repeat their signature lines over and over again like broken records, evident in the second half of this cartoon. Their often-repeated lines are the following;
- Bugs Bunny: "What's up, doc?"
- Daffy Duck: "You're despicable!"
- Elmer Fudd: "I'm hunting wabbits!"
- Yosemite Sam: "Rackin' frackin' varmint!"
- The sound effect where Bugs uses a wind-up key to direct the pale stereotype version of Daffy into the sack of "pale stereotypes" to be blasted into space was previously re-used from the Sniffles cartoon "Toy Trouble", where the sound effect of the wind-up toy duck from that cartoon is re-used here.
- This short re-uses music from "Drip-Along Daffy", "Lighter Than Hare", "Duck Dodgers in the 24½th Century", "Wideo Wabbit", "Barbary-Coast Bunny", "Duck Amuck", "Rabbit Seasoning", "Bugsy and Mugsy", "Double or Mutton", "A Kiddies Kitty", "Bewitched Bunny", "Guided Muscle", "The Slap-Hoppy Mouse", "Scrambled Aches", "Gee Whiz-z-z-z-z-z-z", "Stupor Duck", "There They Go-Go-Go!", “Raw! Raw! Rooster!”, and "Half-Fare Hare".
- This is the last Looney Tunes/Merrie Melodies short made for television.
- This is, to date, the longest-running Looney Tunes/Merrie Melodies short.
- This is one of the only two Looney Tunes/Merrie Melodies short to have a post-credits scene, the other one being "(Blooper) Bunny" produced the previous year.
