The Eds are working on their latest scam. Eddy asked Ed for another tool, but he was playing with his imaginary friend, Jib. Edd is amused by this. Eddy asked Ed what he was doing. Ed said he was sword fighting with his friend Jib. Then he introduced them. Eddy is confused. Jib then insults Eddy because of his eyesight. Edd and Eddy soon catch on. Then Jib said he wanted to show them something. He said to sit on this chair. Edd sat down, then Ed spun the chair in a circle. Edd became very sick after it. Rolf walks by with his chicken (possibly Gertrude) and asked the Eds what they were doing. Eddy explained. Rolf was confused.
Then Ed says Jib also likes chickens. Eddy said that Jib said to sit, then he spins Rolf around which sends him flying. Ed then spun Jib around on the chair. Ed said that Jib was throwing up. Eddy decides to get back to work, but Ed and Jib did not want to. Jib then threw a kick ball at Eddy. Ed said that Jib wanted to play tag. Eddy, who was fed up, chases after Ed. Ed drops a comic book on the ground during the chase. Edd picked it up. It reads, No-Body Man. Edd figured out that that was the reason Ed made an imaginary friend.
While Eddy and Edd were working on the scam, Jib was dominating Ed in tic-tac-toe. Eddy was frustrated with them. When the scam was complete, Eddy removed the cover. It was a Skill Crane. When Sarah, Jimmy, and Kevin came, Edd and Eddy hid inside the machine. Right before Jimmy was about to put his quarter, Ed introduce Sarah, Jimmy, and Kevin to Jib and give them presents made by Jib. Sarah and Kevin walk away with their presents. While Jimmy is about to put his quarter in to win Jib a "prize," Ed prevented him because it was a scam. Ed gets chased by an enraged Eddy. Later Edd and Eddy ask Jonny and Plank if they can help on how they should trap an imaginary friend. Jonny asks them what an imaginary friend is. Eddy tries to make what an imaginary friend is obvious by being near Plank. Despite all this Jonny still doesn't know what they are talking about. He goes to see if Plank knows what it is. Edd shocked asks Eddy if this is their expert. After listening to Plank a little bit, Jonny tells them that Plank said to build an invisible trap to capture the imaginary friend. While Ed and Jib are playing with bubbles, Eddy and Edd are working on the invisible trap. When Eddy tricks Jib into the trap, Jib turns the tables and hurts Eddy a lot ending it by turning Eddy into a ball and throwing him into a window basketball style.
At the end of the day Jib is forced to leave he Cul-de-Sac via the Dander Hound bus line. While Edd is busy comforting Ed over the sudden departure of his new friend Eddy is busy throwing Jibs luggage into the bus. The kids say their goodbyes to Jib and walked away. Ed claims that Jib's "work here is done". Edd becomes frustrated with the constant mentioning of Jib and expresses his wish for the whole situation to end. Eddy takes the moment to exact revenge on Ed by shooting an invisible potato on an invisible slingshot at him.
Edd: [ticked at Eddy's impatience] "I fail to see the correlation between ready and complete, Eddy! Plunger, please." Eddy: "Don't get your sock in a knot, Mr. Perfecto."
Eddy: [to Ed] "Ed, plunger! Are you counting your teeth again?"
Ed: [to Jib] "Take this! And that! Oh, your fly is open! Think again, zombie mind muncher from mucus mansion!
Jimmy: [looking at the prize grabber] "Did it fall off a truck?" Sarah: "That's how my brother was born!"
Jonny[confused]: "Say what?" Edd: "Um... Ed has an imaginary friend, can you help us?" Jonny: [confused] "An imaginary friend? What's that?" Eddy: "Come on Jonny, you know, an imaginary friend?" [motions toward Plank] Jonny: "Hmm... Sorry, I don't know what you're talking about. Maybe Plank knows." Eddy: "This is our expert?" Jonny: "Plank says to build an invisible trap." Eddy: "Makes sense to me. Double D, draw up the invisible plans." Edd: "With invisible ink? Heheh, this is getting contagious."
Eddy: [throwing Jib's invisible cases into the trunk] "I'll miss ya like a hernia."
Edd: [feeling jaded] "I must express my concern of accomplishing anything with Jib around. I'm in quite a quandary." Eddy: [snappily] "Forget your laundry! I hate Jib!" [pushes the swing hard, hitting on Eddy's back]
Ed: [crying on Edd's shoulder] "Who's gonna push me on the swing?" [sob] "Or go fishing with me?" [sob] "Who's gonna help me butter my toast...?" Edd: "Time heals all wounds, Ed."
Ed: [having stopped crying] "Jib said his work here was done." Edd: "CAN WE GIVE IT A REST ALREADY?!" Eddy: [off-screen] "Oh, Ed?" Edd: "Apparently not." Eddy: "Guess what I got?" Ed: [confused] "Hmm?" Eddy: "It's an invisible potato in an invisible slingshot." Ed: "Cool! Where, Eddy?" Eddy: "Don't blink." [releases the potato from the slingshot, hitting Ed's eye, causing him to gaze at the stars]
Although Nazz appeared at the end of the episode, she was absent the entire time, and had no lines, except when she and The Kids waved goodbye to Jib. This is odd, considering she didn't meet Jib from the start.
Ed knows how to play Tic-Tac-Toe in this episode, but in the later episode "Your Ed Here" he plays it incorrectly.
When Kevin tells Jimmy to go for the boombox, Jimmy's eyebrows disappear.
