New Super Mario Bros. Quest

One peaceful day in the Mushroom Kingdom, an ancient artifact known as the "Chrono Crystal" is accidentally awakened by a playful Toad. The Chrono Crystal holds the power to open portals to various dimensions and eras. As Mario, Luigi, Princess Peach, and Yoshi explore the mysterious phenomenon, a powerful sorceress named Magda suddenly appears. She seeks to seize the Chrono Crystal's power to rewrite history and reshape the world in her dark image. With the artifact in Magda's clutches, she scatters its shards across the Mushroom Kingdom and beyond, causing chaos in every dimension. The fate of the entire world rests on the shoulders of Mario and his friends as they set out on a legendary quest to recover the Chrono Crystal shards and put an end to Magda's malevolent plans.
