Mario: Nice of the princess to invite us over for a picnic, eh, Luigi? Luigi: I hope she made lots of spaghetti! Mario: Luigi, look! It's from Bowser. “Dear pesky plumbers: The Koopalings and I have taken over the Mushroom Kingdom. The Princess is now a permanent guest at one of my seven Koopa hotels. I dare you to find her if you can.” We've got to find the Princess. Luigi: And, you've got to help us. Mario: If you need instructions on how to get through the hotels, check out the enclosed instruction book.
