Beanstar

The Bean Star is the star of the Beanbean Kingdom in Mario and Luigi: Superstar Saga. It can only be awakened by someone with a pure voice. Since Princess Peach is the only one remaining with such a voice, Cackletta captures her and uses her voice to awaken the Bean Star. However, Toadsworth and Princess Peach had known about the plan and used magic to disguise Birdo as the princess. When Cackletta used Birdo's voice on the Bean Star, it became angry and shattered into four pieces.
