Mario and Luigi were sitting in their house. They saw the mail was running, and Mario went to get it. He had a chat with Parakarry, before going inside.
"Bills, bills, invitation for cake..." Mario said, looking at the things they had gotton in the mail. "Ooh, it's a letter from our Aunt Tia!"
"Really? What does it say?" asked Luigi. Tia was their favourite aunt, she was the twin sister of their mother, Mia.
"It says, 'Hey Kids (we're like 30!)... Your cousin is coming to live with you... love, Aunt Tia'."
"Wait! Read that middle part again!"
"Your cousin is coming to li-" He stopped, realizing what was going to happen "Oh No! There must be some way to get out of this!" The doorbell rang. "Oh I'll get it." He opened the door. There was a teenager standing there, he looked similar to Mario and Luigi, but his nose wasn't as big and he had no mustache. He was as tall as Mario (his and Luigi's shortness must have come from their father's side of the family, he would clearly be taller than them when he grew up), He wore blue jeans, an orange hoodie, and an orange cap with an "S" on it, like Mario and Luigi's. He had a large smile, with a tooth missing on his top right side.
"Heya, cuz!" He said happily
"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHH!"
AN. Yes, their cousin is a character that I made up myself. I can't decide whether to have this story be one-shots, or a story with chapters. I also haven't decided on their cousin's name. I'm thinking of his nickname being Snake, because he is "Vicious like a snake (not)"
