SMG4 gets annoyed at Mario for being naked while watching spaghetti on his computer and then licking the screen. They start to argue and X, hearing this decides to step in. Mario tells SMG4 that he doesn't know how hard it is to be Mario and SMG4 comments that it's hard being him too. This gives X the idea that everyone should swap colour codes for the day so that Mario can learn how it is to be SMG4 and vice versa. While Mario gets excited about what he will be able to do, SMG4 isn't as keen on being a fat Italian. X suggests that FM and MCG switch colour codes and while reluctant, FM agrees. X ends up swapping colour codes with Luigi who drops in, even though he isn't too happy about it. They all take off their overalls to change colour code.
After swapping everyone has different feelings, X feels a strange urge for men, Luigi toys around with X's guns thinking that they are hats, FM finds MCG's overalls to be stuffy, MCG starts punching around for fun, SMG4 feels the weight that Mario has to carry and Mario himself imitates SMG4. Mario leaves to mess around as SMG4. He finds Toad who mistakes him for SMG4 because of the overalls, after telling Toad that they switched suits he asks Toad if he wants to be something else. Toad says yes to this and Mario swaps Toad's body with a rock, but before he realises that he cant move as a rock Mario leaves. SMG4 comes by and Toad tries to get help, but instead SMG4 almost throws Toad in the trash.
Mario decides to toy with SMG4's powers and raises the trees outside the castle from the ground.FM meanwhile is getting used to being MCG, when a crazy Indian mistakes him for being the guy who stole his toilet and tries to kill FM. Luigi, while walking outside encounters a zombie who he mistakes for being a cute person whose name is Brains and starts to play with the zombie. Back in the castle X and Toad watch as MCG runs around the castle punching rapidly. SMG4 starts to realise how hard it is to be Mario as he finds it hard to move with all of the weight, feels constant hunger and is mentally disturbed by the size of Mario's flab. He comments that Mario is probably having a miserable time as him, but Mario meanwhile is riding Dorrie in the sky while messing around with the sky's color.
FM, having retreated to Bob-omb battlefield writes in his diary that if he is killed he wants his friends to know that he hated them. As he writes this the crazy Indian spots him. FM surrenders and shows the white flag begging the Indian to not rape him, but the Indian responds by shooting the flag and chases after FM while yelling an Indian battle cry. Back outside the castle, Luigi is spinning around with brains so much that he vomits and in the castle Toad realises that he needs the bathroom and asks X to throw him over there. Unfortunately X throws him too far and he ends up at Bowser's place. Bowser takes interest in Toad while not realising that it's Toad. Bowser decides to call Toad for fatty and dresses him with a bikini, much to Toads annoyance. MCG continues punching, now backwards and SMG4 nearly begins to cry as he has now forgotten what 1+1 is and is constantly running into invisible barriers: SMG4 decides that he wants to get his colour code back and apologise to Mario. Mario meanwhile uses SMG4's powers to split the sea, while he enjoys himself he starts to long for his old self and decides to get his clothes back after going surfing.
At the castle X replaces Toad with another rock before going himself to change back. MCG, after having punched forwards, backwards and Michael Jackson style shuffled, decides to punch upside down and jumps into the painting to Bob-omb battlefield. At the battlefield FM manages to dodge the crazy Indians attack form above, causing him to crash on the ground. The Indian however survives and is still determined on killing FM when Mario lands on the Indian. After recovering the Indian states that he is going to make everyone indian, take over the world and make everyone wear female underwear. However as he talks about this, MCG runs into the Indian while punching in ways that FM himself wasn't aware that he could do. This becomes so violent because of the grass that Mario has to censor the violence with SMG4 who arrives getting hurt by seing the violence that the grass is performing. Back at Bowser's place Toad decides to escape, he distracts Bowser by saying that Mario is behind him before hopping of the edge. Bowser fortunatley doesn't care and quickt replaces Toad with another rock named Bob.
At the castle Waluigi and Wario watch as Luigi is hanging out with brians. Wario questions the fact that X hates zombies, to which Waluigi replies that X has become gay since then. As Luigi plays on the top of the castle with brains, Toad falls by and knocks down brains. Luigi checks on the zombie to find that it's dead and cries out in sadness. At Bob-omb battlefield everyone else prepares to change back. SMG4 apologises to Mario and admits that it's hard being Mario. Mario happily replies that he found out that SMG4 can raise trees, ride tunas and cut the sea, SMG4 gets confused at this and Mario decides to not tell him anymore. Luigi arrives depressed over the loss of his friend, but none of them show any interest and they all decide to change back. While everyone takes of their clothes, the crazy indian manages to record them naked and runs off claiming his revenge. Mario finds it nice to be back in his clothes while SMG4 gets annoyed after realising that Mario pee'd in his overalls, to which Mario states that he thought that he had a built in toilet in the overalls. X comments that he can still feel the gayness inside, with Luigi explaining that it might come from the dump he took in X's clothes. MCG asks what everyone learnt from this experience and FM answers that he learnt to never go near crazy indians again. They all start dancing and SMG4 questions where Toad is. Back at the castle Toad puts the bikini on brains.
- This blooper is one of the few times Bowser is with Toad.
- Mario in 2011 mostly went on SMG4's computer naked and searching up spaghetti pictures.
