Max asked Sarah to bake cookies and bring them to the school bake sale to help support the basketball team and impress Misty Lewis. However, Sarah magically enchanted the cookies which caused them to grow large, sentient, and start rampaging through the school screaming. Max is frustrated with Sarah because this is reminiscent of her previous magical mishap known as the "macaroni incident". They now need to work together to stop the giant magical cookies.
