The episode continues to when Mabel predicted that the Phantom Star Gerath would collide with Cappy Town and destroy the world. Dedede doesn't seem to mind, however. The next morning, Dedede reveals to the residents, a gigantic, hideous statue of himself. Everyone protests that he did not build the park they asked for, and that because of him, Geras will destroy the world, while Mabel also says that no matter how much Dedede will struggle, he will be scorched by Geras' flames. Dedede still doesn't care, until Escargoon sees that the star has gotten closer, now being the size as the sun. He then panics. Everyone in Cappy Town goes to Kabu to ask what will happen when Geras collides and when. Tiff suddenly comes and says that the end of the world is in two days. Everyone leaves, thinking that this is the end, but Tiff does not intend to give up. She tries to find a way to prevent the end, along with Meta Knight, Sword, Blade, Tuff, and Lololo and Lalala. She then tells them to load the castle's cannons, then they will blast them off, hoping to change the trajectory of the star's orbit. Time falls short, as Geras has gotten really close to Popstar, so everyone takes refuge in the castle, and confesses their faults. Dedede feels real bad for putting up a statue instead of a park, so he blows up the statue and builds the park. He then takes Kirby, and shows him the park. He is happily amused, and Dedede gets tearful for making someone happy for the first time in his life, and swings. The end is now near, and Tiff, Tuff, Meta Knight, and everyone else blasts the cannon, but the cannonballs fail to hit Geras, but Tiff sees Kirby, who was blown away, along with Dedede. She calls for the Warp Star, while Kirby leaves Dedede hanging on top of the castle. Tiff gets Kirby to inhale the cannonballs, then spits them at Geras. The explosion of the cannonballs slightly change the trajectory of the star, but while it moves away, Dedede gets scorched. The end has been avoided, and Tuff tells Mabel she was right that Dedede would be scorched no matter how much he struggles, then everyone starts to laugh as things return to normal.
