When Bowser grows back to normal, he takes the entire castle with him back to his home in the galaxy. Meanwhile, Mario and Luigi are having their normal life in Brooklyn. Mario discovers Yoshi and decides to adopt him as his pet. Luigi finds a new love interest which is Daisy. They are unaware that Peach and the Toads have been kidnapped until Rosalina comes in to inform Mario and Luigi about this news. Mario and Luigi then head out of their world to rescue Peach from Bowser. Joining them on this mission is Rosalina as their leader, Daisy, Donkey Kong, Yoshi, and Toadette who is the only survivor of the Toads who were kidnapped. Along the way, they meet Wario and Waluigi. Bowser Jr is introduced and his goal in this movie is to protect Bowser and make sure the main characters don't reach him. Peach's origins will also be explored in this film. My ideal runtime for this movie is 1 hour and 44 minutes which is much longer than the first.
