Cave's Revenge (A Super Mario Sunshine + Super Paper Mario Inspired Story)

I didn't actually properly make this story. This whole story was actually a dream I had recently. I know, pretty weird to have a dream about Mario and Luigi. Anyways, this takes place on Isle Delfino. Since this is a dream, it doesn't exactly have a proper time. Though at this point, I think it takes place during what my brain thinks would be Super Mario Sunshine 2 since it has Luigi in it. This story begins with most of the familiar cast (Princess Peach, Mario, Luigi, Toads, Piantas, etc.) on a beach about to leave to go back to The Mushroom Kingdom. Mario and Luigi had just defeated Bowser and saved the Princess once again.

There is a cruise ship at this beach, that the Mushroom Kingdom residents are using to go back home. Mario and Peach are currently on the Cruise Ship, ready to leave. Luigi is still on the beach, talking to Isle Delfino residents. However, the Cruise Ship then begins to leave without him. Find out what happens next in this story, which I call, "Cave's Revenge".

(Also just as a heads up the Cave itself doesn't take revenge on anyone; I just couldn't really think of a good title so I thought that I should make a title slightly based off of an area that's described in this story)
