Yumi is in dire need of a new guitar and learns she must complete specific challenges to earn it. She seeks guidance from Master Mei Pie, who assigns her a series of tasks to gather various items. After successfully collecting everything on the list, Yumi comes to a startling realization: she had been so focused on the tasks that her guitar playing had taken a backseat.
