The second level, "Pin the Tail on the Ed", begins with Jimmy having his birthday party with the kids, but Rolf tells the Eds that they are not allowed to go. Not one to take no for an answer, Eddy decides they will find their own way into the party. Ed suggests that they sneak in through the sewers. Despite Edd's worries, Eddy leads his friends through the sewer to sneak into and crash Jimmy's party. The Eds successfully sneak into the party. While everyone is inside Jimmy's house, the Eds break all of Jimmy's pinatas, but the Kankers pop out of one and chase them. Edd uses his slingshot to shoot down beehives in the trees so the bees chase the Kankers away. After defeating the Kankers, Kevin tells the Eds that the party has ended and everyone has left. Jimmy "rewards" them with a blob of icing with five birthday candles in it, which Ed proceeds to eat.
In "Must Be Something I Ed", Rolf tells the Eds that it is the candy store's "Customer Appreciation Day", and they are giving out free jawbreakers. Since it is almost closing time, Eddy decides to head there straight away and take a shortcut. After they get past Sarah and Jimmy, Kevin, Johnny, and Plank, and a vicious bulldog, they finally arrive. At the candy store, Eddy accidentally eats a jawbreaker covered with foot powder and his face turns green with orange spots due to an allergic reaction. The trio manage to sneak back to Eddy's house without being seen by the other kids. However, they all appear at the window with cameras as Eddy is about to close the curtains, laughing while taking pictures of Eddy's face.
"Ed on Arrival" begins with Rolf showing off his Urban Rangers badge to the Eds, and Eddy says he wants one. Rolf challenges the Eds to make it across the Peach Creek Estates construction site, where he has set up an assault course, promising them the badge if they make it. Eddy refuses at first, but when Rolf tells him that he will give the badge to Kevin, Eddy accepts the challenge. However, Rolf tells Kevin in private to make sure they do not succeed. The competition heats up when Kevin prepares tricks, traps, and tribulations, but the Eds manage to complete Rolf's tasks thanks to the Eds' ability to stand on each other to create "The Tower of Eddy". After a head-butting competition with Rolf's goat, Victor, the Eds race Kevin to win the badge. The Eds win the race, but in order for the badge to be shared fairly, Rolf rips the badge into three pieces. Ed wants to trade his piece with Eddy's, but Eddy is so annoyed that he shoves it up Ed's nose and storms off.
In "Nightmare on Ed Street", Jimmy's toy rabbit, Mr. Yum Yum, is trapped on the window sill of the old abandoned house. Since Jimmy is too frightened to go inside himself, Eddy promises to retrieve it for a quarter. Jimmy refuses to pay Eddy, saying he will pay him when he gets Mr. Yum Yum back in one piece. Inside the house, Eddy reveals to Edd that he told Ed to steal Jimmy's rabbit so Jimmy would pay them to get it back, but Ed tells Eddy that he put Mr. Yum Yum on the mantel, not the window sill. Suddenly, the Kanker sisters appear, holding Mr. Yum Yum and threatening to cut Mr. Yum Yum with a spinning saw. After the Kankers make flirtatious advances towards the Eds, they agree to trade Mr. Yum Yum with the Eds in exchange for giving them "good boyfriend presents" without any kisses. After exploring around the abandoned house, the Eds bring the Kankers their presents (a ship in a bottle for Lee, a can of axle grease for Marie, and a taxidermy book for May) and disable the saw. They successfully retrieve Mr. Yum Yum for Jimmy, only for it to fall in half. Jimmy runs off crying, leaving the Eds without their promised reward.
In the final main level, "Ed Marks the Spot", Eddy is going to share his secret stash of jawbreakers in his suitcase with Ed and Edd, but someone has taken them all. As Eddy shakes the suitcase, a piece of a map falls out. Edd suggests that they look for the other pieces of the map in order to recover Eddy's missing jawbreakers. The Eds put their heads together to find out who took the jawbreakers and confront the thief to get them back. They save the first piece from Johnny (who wanted to turn it into a paper airplane), get the second piece from Jimmy (who was trying to do origami with it), and get the last piece from Rolf's goat, Victor, by head-butting him off a cliff. They put the pieces together and realize the Kankers took the jawbreakers. Eddy angrily storms into their trailer, where the Eds accidentally activate a trap door and fall underground. They then must run away from the Kankers who are madly trying to kiss them. They enter a large room where they battle the Kankers to get the jawbreakers back. After defeating them, the Eds grab the jawbreakers and run back to the Kankers' trailer, which has strangely been decorated to look like a church. They realize that the Kankers have trapped them in a wedding ceremony, as they kiss the frightened Eds.
In the first bonus level, "Revenge of Ed-zilla", Eddy recreates his Edtropolis scam. All is well until Ed believes he is a monster and goes on rampage throughout the city. He then battles the Kankerator at the Chunky Puffs factory, using giant Chunky Puffs as his weapon against them. After Ed defeats the Kankers (destroying Edtropolis in the process), Eddy goes in a rage and he angrily whacks Ed in the face with a metal dustpan lid.
In the second bonus level, "Robot Rebel Ranch", the Eds find themselves stuck on the robot planet, and their only hope is to get to the space rocket. Ed thinks he should take the lead, but he ends up being zapped by the robot rebels and taken capture. Edd (using Ed's laser pistol and a red light saber) and Eddy (using a shock bomb and yellow plasma flail) must now rescue Ed from the clutches of the robot rebels. After they free Ed, they have to find the space rocket so they can leave the planet. Before returning home, they have to battle the giant robot leader, a huge, red robot turret with a cowboy hat and two laser cannons. They successfully complete their mission with the help of Edd and find the rocket. Their imaginary game is disrupted when Sarah yells at Ed to come home for dinner. The game ends with Ed crossly storming away, all thanks to Sarah.
Reception
Ed, Edd n Eddy: The Mis-Edventures received generally mixed reviews from critics. IGN's Charles Onyett criticized the game for its "unclear" objectives, repetitive voice acting, and short length, but he praised the game's graphics for "reproduceing the visual style of the show quite accurately...to an often hilarious degree."
