From here, a grand odyssey takes place. However, two gorillas affiliated with Mario's past job as a zookeeper are also after them, and try to foil their heroics along the way. Can these two very different families put their differences aside to rescue the Mushroom Kingdom from the wrath over an evil overlord?
