 In skipping, punching, sit-ups, and running, the monkeys learn to train by copying the actions of the main character whose motions are controlled by a rhythmic pressing of the "A" button.Over time, a monkey will learn to imitate these actions for a longer period eventually requiring no prompting for it to begin.The player can then choose to send the monkey out to shop for certain items or let it simply buy what it wants—this is the only way to obtain new items.
