| Please note the following:
"Mario's Nightmare" is the 3rd episode of SML Shorts.
Mario goes to bed and has a bad dream.
At 2:00 am, Mario was about to go to sleep and he complained to himself about the overtime at his workplace, hoping that he doesn't make Peach notice that he was late for home. Peach wondered where he had been, and Mario informed her that he had two overtimes, but she didn't believe that, and instead, she believed that he was seeing Daisy, then, they went to sleep.
There was some music made by Bubbles that was making Mario disturbed, so Mario told him to stop, then he stopped, then Mario finally went into sleep.
The nightmare begins. Basically, Mario was running, then he lost a life from a Goomba, then he lost a life again, then on his last life, he did get past this Goomba, but lost against the next Goomba, then it was game over. Mama Luigi was playing the game and laughing manically.
Next, Mario woke up, saying thaty it was his worst dream ever. He thought it was because of Bubbles playing music, but that's not what really happened. In fact, in real life, Mama Luigi was also playing a game.
