Just then, two packages (one large, one small) arrived. Before Mario could open it, Bowser Jr pops out of the smaller package, while the rest of the Koopalings pop out of the bigger one. The Koopalings then steal all the Power-Ups from the trees, Mario tries to stop them, but Kamek arrives and kidnaps Princess Peach, bringing her to one of the airships. After the mess, Mario and Luigi had been tied into one of the plucked Power-Up trees by the Koopalings, who had stolen all of the Power-Ups. Mario manages to break the rope, but he realized that the Yoshi Eggs also has been stolen! Meanwhile, Bowser is seen using the stolen Power-Ups on his army so he could defeat Mario easily.
