At the Opening Ceremony, Bowser and Eggman are at the front watching Mario and Sonic present the Olympic Games.

Challengers Bonus
Bowser Jr. arrives in England to compete in the games. Unfortunately, he took a wrong turn and ended up in Stonehenge instead of London. He sees Yoshi training for the games and challenges him to an Olympic event. Jr. wins and calls on his Bullet Bill to bring him to London.

Later, Omochao and a regular Chao are being threatened by two of Dr. Eggman's robots for unknown reasons. Shadow and Silver arrive to defeat them, but Jr., flying overhead, accidentally falls off of his Bullet Bill and destroys both robots. The two Chao are greatful and even the two hedgehogs are impressed. Wanting to see how strong he really is, they challenge Jr. to a 2-on-1 Olympic event. Surprisingly, Jr. wins. Shadow and Silver are good sports and congratulate the young Koopa. A nearby Goomba convinces Jr. to look for more robots so that he'll be even stronger.

Arriving at the stadium, Jr. and the Goomba see Dr. Eggman measuring Metal Sonic's time running around the track. Jr. challenges Metal Sonic to an event. Thinking this would be perfect practice for the robot, Eggman agrees, on the condition that Jr. becomes his servant if he loses. Jr. accepts, telling Eggman that if he wins, he has to tell Bowser of his victory. With that, the reptile and robot set off. Jr. eventually wins. Eggman tries to examine Jr. to see what he needs to do to upgrade Metal Sonic, but Jr. angrily stops him, demanding a snack in exchange for Eggman trying to trick him. The scientist reluctantly agrees.

Wild Ones Bonus
Bowser angrily stomps through London, followed by a Goomba, a Lakitu, and a Magikoopa. Bowser is angry because of a toothache. His minions decide to cheer him up by secretly letting him win some Olympic events against various challengers. Their first target is Donkey Kong. The Magikoopa promises a pile of bananas in exchange for defeating Bowser in an event, but when the ape agrees, the wizard summons a Thwomp to fall on DK, making him dizzy and less likely to win. Bowser arrives and wins against DK. Behind his back, however, Magikoopa makes it up to DK by getting him the bananas that were promised.

Later, the Magikoopa, as well as the Lakitu and a Dry Bones, somehow convince Knuckles and Vector to rendevous. To convince them to fight, the Magikoopa uses his magic to make the Lakitu and Dry Bones to look like Charmy and Espio, respectively. The two real Chaotix members notice the two fake members acting funny, but agree to fight Bowser. The Magikoopa then summons giant versions of a Chain Chomp and Piranha Plant to bite Knuckles and Vector, respectively. Similar to DK, this makes the two animals dazed and less likely to win. After Bowser defeats them, the Goomba (who had led Bowser to the arena) quickly escorts him out before Knuckles and Vector ask too many questions.

For Bowser's last false victory, the minions plan to make Mario lose in a tennis game. Unfortunately, the Boo assigned for the job failed to trick Mario into coming to the court. After the other minions come, Dry Bones distracts Bowser while the others think of a plan. The Magikoopa decides he'll have to transform one of the minions into Mario. Dry Bones can't do it because he is talking to Bowser; and neither Boo nor Lakitu can do it because of their floating. The small mushroom is terrified to do so, but agrees when Bowser's patience wears thin. Bowser challenges "Mario" to a game of tennis and loses. After the match, Bowser Jr. arrives and is shocked to see his dad lose, while the minions celebrate over the success of their plan.

Tricksters Bonus
In his secret headquarters inside Big Ben, Eggman defeats Metal Sonic in a match of Taekwondo. However, he is unsure what to do to upgrade his creation. His other robot minions, Orbot and Cubot, see Waluigi on the monitors and suggest him for practice. The foursome confront the man in purple and convince him to battle, saying it would make good practice for defeating Luigi in the Olympics. Metal Sonic wins, and Eggman deduces that Metal Sonic possesses speed, but not strength.

Eggman and the robots come across Wario and ask him to challenge Metal Sonic so that the robot may go against Wario's strength. However, defeating Mario isn't good enough for Wario, so he and Eggman settle on a bet: If Wario wins, Orbot and Cubot come work for him. If Metal Sonic wins, Wario has to give Eggman something of his. Metal Sonic emerges victorious. Wario gives Eggman an old urn he got from an antique shop, claiming its magic. Eggman seems to recognie it and accepts it.

Back in his headquarters, Eggman places the urn inside a machine. The machine slightly unseals the lid on the urn and gray fog pours into the room. Some of this fog takes the shape of Sonic and Eggman challenges it to an event. Eggman appears victorious and the Sonic imposter vanishes into thin air. Eggman explains to his minions that this urn contains the legendary Phantasmal Fog, stolen 300 years ago by the legendary pirate William Kidd. The urn eventually ended up in the British Museum, where it was recently stolen. Eggman resolves to completely unseal the urn after he and Metal Sonic are done training for the Olympics.

Girls Bonus
At Hyde Park Peach, Amy, Blaze, and three Toads are setting up the invitations for all of the athletes, however Amy suggests she take Sonic's invitation to him personally but the others don't want Amy to go and insist that she stay and help the others work. However, after more begging, Blaze suggests that if Amy can beat her in a competition she will let her go. Then, after Amy beats her, Daisy shows up and battles with Peach and after Peach wins they all go out for a break, but when they return the wind had knocked off all of the invitations to the ground. After they pick them all up they realize that they are missing Bowser's and Eggman's invitations they make new ones. Later, Peach and Amy meet Bowser and Eggman in the park and end up playing a round of Beach Volleyball, after they win they go fetch their invitations, but at the same moment the toads go to deliver them, they drop Eggman and Bowser's next to them. Bowser and Eggman look at how well it's written and think that their love letters to Sonic and Mario. Bowser and Eggman go off together looking around London before they do something evil. The girls assume that Bowser and Eggman took their own and then all go out shopping together before the Olympic Games start.

Demo
On March 1, 2012, a demo of the 3DS version of the game was released on the Nintendo eShop. Five events are playable in the demo: 25m Rapid Fire Pistol, Football, Trampoline, 50m Backstroke and BMX. The player cannot choose his or her character or name, as that is always M&S. Each event is played using one of four characters, and each set of characters in an event belongs to a particular class. The 25m Rapid Fire Pistol uses the Tricksters class, the Football event uses the Wild Ones class, the Trampoline event uses the Challengers class, the 100m Backstroke event uses the Girls class, and the BMX event uses the Heroes class. The demo can be played a maximum of 30 (20 in Europe) times once downloaded.
