You encounter the Princess

You are John Doe, a 18 year old guy. You are bored, seeking any kind of excitement and hoping you could find a girlfriend. You also are kinda broke, so you had to watch old cartoons you got from the bargain bin. You lived with your parents and helped them out, even if they were hinting you should move out.

Out of the ones you watched, you liked the Mario cartoon the best. In fact, you were surprised that even though Nintendo often liked to pretend the cartoon didn't exist, they did borrow a lot from it. Like Bowser and Peach being able to use powerups, Luigi being a scaredycat, and so on.

On a rainy day, you sighed, wondering if you were gonna go on and do nothing forever.... Then you looked out of a window and saw something that boggled your mind.

A green pipe, right in your parents' backyard.

After putting on rainboots, a raincoat, and an umbrella, you walked out to go check it out.

You walked up to the pipe and looked down it.

In the Mushroom Kingdom, Princess Toadstool was talking a walk around her castle, merely enjoying the bright sunny day.

"Sure is a wonderful day... The Sun is shining, the birds are chirping..." Toadstool said with a smile. Then she frown a little bit and muttered, "and yet I'm lonely. Mario loves food way too much, Luigi's easily scared, Toad values his retainership way too much... I wish I could get... "

She then noticed a brand new warp pipe.

"Huh... Wonder where that goes? Maybe I should ask the Mario brothers or Toad if they..." Toadstool began before shaking her head. "No! It's my time to shine! It's my adventure!"

So she walked to the pipe and looked down it.
