Dewey, Webby, Launchpad and Scrooge are at Funso's Funzone. While Dewey and Launchpad take part in a V.R. game called Double-O-Duck, Webby introduces Scrooge to Skee-Ball where he becomes addicted to collecting tickets as if they were actually money. Launchpad messes up in the game, but Dewey comforts him and tells him that they will just have to go through the level again. Underneath the Funzone, F.O.W.L. is keeping a close eye on the Duck family with Black Heron and Steelbeak plotting to take them out. Black Heron plans to use an intelligence ray on Scrooge so that he can be dumber, having tested the opposite effect on a couple of chipmunks and two mice to make them smarter.
Steelbeak sneaks into the Funzone and, posing as a character in the V.R. game, confronts Dewey and Launchpad. They end up fighting throughout the facility, unaware that they are causing actual damage, until Steelbeak drops the two of them through the ball pit and imprisons them in glass cells. Still thinking that they are in the game, Launchpad tries to escape by firing a rubber band at the release button, but cannot accomplish the task. Unknowingly, the rodents from earlier arrive, having built a small flying vehicle for themselves, and help the two escape as they do so too.
Steelbeak tells Black Heron about what he has done and she berates him as this would most likely mean that Scrooge will come looking for them as that is what he is known for doing. After calling him a moron, Steelbeak takes the intelligence ray and fires it at Black Heron, making her dumb. He finds Dewey and Launchpad and he and the Egghead henchmen fight them. Having accidentally switched the setting back to smart, Steelbeak fires at Dewey, but Launchpad jumps in the way and gets hit. As Steelbeak takes Dewey hostage, Launchpad awakens, having grown in intelligence and now speaks with a more refined accent. Realizing that they are not in a game and that F.O.W.L. is at work, he sets off to rescue Dewey.
Launchpad chases the two all the way to Steelbeak's lighthouse. He now plans to use a bigger intelligence ray by firing it on Duckburg and making the entire population dumb. With the help of the rodents, who Launchpad thanks for the "rescue", they defeat Steelbeak, but the laser is still going to fire. Launchpad sacrifices his intelligence by standing in the way of the ray as the whole base falls apart. Launchpad's intelligent side tells him to never forget him. Launchpad and Dewey awaken back at the Funzone and a defeated Scrooge reveals that he spent all his tickets on a mustache comb. Intelligent Launchpad calls to tell Scrooge about what he knows, but Launchpad completely forgets.
Meanwhile, Bradford Buzzard brings Steelbeak and a returned to normal Black Heron back to his base. He angrily berates the two for their failure and tells them that he wants no more rays and that they will have to attack Scrooge with more cunning than usual.

- The title is a reference to the James Bond series (Double-O-Seven) as well as the 1967 film You Only Live Twice.
- The episode bears several similarities to the classic DuckTales episode "Double-O-Duck" including the title and plot revolving around Launchpad facing off against F.O.W.L. agents. Series producer Matt Youngberg had cited the original episode being used as inspiration for a future episode.
- When Launchpad sacrifices his intelligence, the melody from Sky Fall by Adele is heard (originally used in the James Bond movie of the same name).
- This episode serves as a nod to the earliest concept of Darkwing Duck, which was originally titled Double-O-Duck and was to have Launchpad as the main character.
- The characters from Rescue Rangers appear, and are crucial in helping Launchpad.
- An instrumental score of the "Rescue Rangers Theme" is played twice; once when the rodents assemble their Ranger Plane in Launchpad's cell, and again when Launchpad tells Steelbeak about the arrival of the Rescue Rangers who then release electric wires to shock Steelbeak on the bill.
- This is the fourth episode to feature an alternate song during the end credits rather than an instrumental version of the theme song. The other episodes to do so are "Who is Gizmoduck?!", "Last Christmas!" and "The Dangerous Chemistry of Gandra Dee!".
