The day after that, Luigi saw the purple shy-guy walk by again; party hat, spaghetti, and all. And the day after that, and the day after that, and the day after that! It was getting creepy… where was it going?
The purple shy-guy had walked down the street with its party hat, and plate of spaghetti every day for two months. Finally, Luigi came to a conclusion:
"I have to find out what that shy-guy is doing!" he cried frantically. He rummaged in his desk until he found a notebook and pencil, then grabbed his 'detective hat' from the back of his closet, "This is a job for…" He safety-pinned a blue-and-yellow striped towel around his shoulders, "Super-Detective Luigi!" He frowned, "Hm. I've got to work on that name… It doesn't really have any ring to it. Oh well." He shrugged, "It'll have to do for now. I'd better go get my super-detective brother!"
Luigi raced down the hall, striped towel cape flying behind him, knocking over a vase of plastic flowers as it fluttered by. "Mario!" Luigi burst into the workshop, "There's a mystery to be solved! Let's go!"
Mario looked up from his game of solitaire, "Mystery? You mean that purple shy-guy wearing you've been obsessing over?"
"I have not!" Luigi crossed his arms over his overalls, "just because I constantly think about it every hour of the day doesn't mean I'm obsessed!"
"… you talk about it in your sleep sometimes." Mario added.
"I do?" Luigi put a finger to his chin, "Well, okay, so I'm obsessed. Please help me figure out what he's doing!"
"Luigi! I'm busy! I don't have time to run around town trying to figure out what some shy-guy is up to." Mario said, flipping another card, "and stop groveling like that; this floor hasn't been cleaned since 1991!"
"But…"
"OUT!"
Luigi left the workshop feeling dejected. He sighed melo-dramatically, "I guess I'll just have to… somehow… find out what that shy-guy is doing… without my big brother to help me." He dragged his feet as he walked down the hall, continuing pitifully, "Nobody to help me out when I trip during a high-speed chase… Nobody to brainstorm with over mind-boggling clues… Nobody to talk to during late night stake-outs…" He leaned back into the workshop wailing pathetically, "Nobody to share peanut-butter and jelly sandwiches with on snack breaks…" he leaned over Mario's shoulder, "No-o-body to-"
"Alright, ALRIGHT!" Mario shouted, covering his ears, "If I help, will you stop bugging me!"
"Yup." Luigi smiled happily.
"Can I get that in writing?" Mario whipped out a pad and pen.
"Sure…" Luigi took the pen, "I, Luigi, hereby promise that, if my brother Mario agrees to go detective-ing with me, I will stop bugging him. About this." He handed the pen back to his older and shorter brother, "Good?"
Mario nodded, "Good." He rolled up the paper and shoved it into his overalls, "Let's get this over with."
"Wait! You need a costume!" Luigi cried.
"Why do I need a costume?"
"To protect your secret identity!"
"My identity isn't…" Mario sighed, seeing that he wouldn't get anywhere by arguing, "Fine. We can look for a costume."
"Yay!" Luigi jumped for joy, "We'll start detective-ing tomorrow!"
"Tomorrow?" Mario stopped, eyebrows raised, "Why tomorrow?"
"You want a quality costume, right?" Luigi grabbed Mario's hand and dragged him rapidly down the hall to their room, "Come on!"
