(It's a nice day at Peach's Castle, and fireworks are going off. Why? Well, it appears the Goodwill Ambassador from the Beanbean Kingdom has arrived to Peach's Castle.)

????????: I wish to improve my kingdom's ties with this one. (Bows) I bring a gift from Queen Bean.

??????: (Walks to Princess Peach with a chest)

Princess Peach: (Walks to the chest, it opens and green gas spews out)

Admiral Ackbar: (Pops out of nowhere) It's a TRAP!

(This is no Ambassador! Enter Cackletta, the main antagonist of the plot! The Beanish witch summons bolts of lightning before her assistant, Fawful, laughs whilst vacuuming up the gas and Princess Peach collapses, knocked out! Lightning flashes in the background while Cackletta and Fawful escape! Unbeknownst to them, however, a Toad heads to Mario and Luigi's house, where a certain other duo is visiting...)
