Darkwing's computer goes out of control, causing him and Gosalyn to trade bodies as do Launchpad and Honker. Now he has to figure out how to stop Steelbeak from stopping the Earth's rotation while in Gosalyn's body.
This episode contains examples of the following tropes:
- Air-Vent Passageway: Played with, while Gosalyn's and Honker's body are able to use them easily, adult bodies like Darkwing and Launchpad are too big to fit.
- Bait-and-Switch Comment: Inverted. The Eggman sound annoyed at first when they hear a kid stole a little girl's ball, but instead they congratulate him.
- Drives Like Crazy: Gosalyn in Drake Mallard's body. Justified as she has no idea how to drive a car.
- Doomsday Device: F.O.W.L literally uses a super-rocket to stop the earth-rotation and will only restart it if the government of the world pays 1 trillion dollars.
- Even Evil Has Standards: Subverted. Long story short, Darkwing and Gosalyn and Launchpad and Honker switched bodies and have to get past some FOWL agents guarding a gate. Darkwing (who is still inside Gosalyn's body) decide to use Gosalyn's and Honker's bodies to appeal to the guards' better nature. After running around, crying that Honker stole "her" ball, the two guards seem to be disgusted by "Honker's" actions...only to congratulate him for his nastiness, suggesting that he takes after themselves, and offer to beat up "Gosalyn" for him.
- "Freaky Friday" Flip: Darkwing and Launchpad switched body with Gosalyn and Honker, respectively.
- Hypocritical Humor: Gosalyn has switched brains with Darkwing and the two pretend to be one another to avoid suspicion. Gosalyn in Drake Mallard's body scolds Darkwing in Gosalyn's body by telling him that "[he is] grounded for life and [his] allowance is suspended until further notice", then tells her adoptive father it is fun to yell at him like he yells at her. Darkwing in Gosalyn's body claims that he never yells at her like that, but when he sees that his car has been crashed into the stairs, he nearly repeats Gosalyn's scolding word for word, getting cut off when a message from S.H.U.S.H arrives.
- Lethal Chef: How Steelbeak portrays himself in the video as he uses a heavily dented world globe, some ice cream and cooking it over a fire to show what will happen to the world if they don't give in to F.O.W.L's demands. He also promised to give them the chicken salad (though that last one might have been a gag.)
- Pop-Culture Pun Episode Title: The episode title alludes to Trading Places.
- Squashed Flat: What Darkwing and Launchpad use to escape the shuttle to save Honker and Gosalyn.
- Steelbeak was also ready to shoot and clobber one to death.
