New Super Mario Bros. U Deluxe Part 2
11New Super Mario Bros. U Deluxe Live Playthrough Part 2
Mario, Luigi, Yellow Toad, and Blue Toad are with Princess Peach in Peach's Castle dining together. Bowser and the Koopalings suddenly arrive in their Airships, with the former sporting a Mecha Hand that smashes and launches the brothers and the Toads away from the castle. Mario and his friends crash into the Acorn Tree, launching Super Acorns through the area. They then tumble out of the tree, passing by a Bubble Baby Yoshi and Balloon Baby Yoshi, and they then look into the horizon to see Bowser beginning a siege on Princess Peach's Castle, setting the Mario Bros. and the Toads to go on a new adventure and to Princess Peach.
As the game progresses, the view occasionally shifts to Peach's Castle, showing the flags being replaced by Bowser's flags (after Tilted Tunnel), and the castle being surrounded by a thin tornado-like cloud that is made thicker by Magikoopa's magic (after Stoneslide Tower), entirely obscuring the castle (after Giant Skewer Tower or Freezing-Rain Tower). Mario, Luigi, Yellow Toad, and Blue Toad also encounter Bowser's forces, including the Koopalings, Boom Boom, Magikoopa, and Bowser Jr., who occasionally attacks the heroes with his father's airship. All of them are defeated, and Bowser Jr. causes the airship to crash after making the mechanical hand punch through it. After reaching Peach's Castle and defeating Bowser, the group moves onward, but Bowser Jr. appears and urges Magikoopa to spread his magic across the area. After heading to the castle exterior, Mario and the others see Peach in a tower. Before they can save her, she is locked inside the tower and Bowser appears, now at a giant size, alongside Bowser Jr. Eventually, Bowser is defeated and Bowser Jr., embarrassed, flees. The character that defeated Bowser gets to Peach and bows down to her, and is then kissed by her, to their shock and delight, as the clouds surrounding the castle disappear, restoring it to its former state.
Outside the castle, the Koopalings and Bowser Jr. are fleeing on the airship as Bowser recovers. Noticing the escaping airship, he climbs up onto one of the castle towers and leaps onto the ship, but his weight causes it to plummet into a hill nearby; they then fly away hanging onto Bowser Jr.'s Junior Clown Car while Mario and Blue Toad watch. They then turn back to the others, who are celebrating their victory, with Mario delivering a final victory pose.
