In “The Princess and the Frog,” the firefly is named Ray.
Ray is a middle-aged Cajun firefly who lives in the Louisiana bayou. After Tiana and Prince Naveen are transformed into frogs, Ray helps guide them toward Mama Odie, the voodoo priestess who may be able to break their curse. His warm, community-minded personality makes him one of the film’s important supporting characters.
Ray is also a romantic figure. He is devoted to Evangeline, the evening star, whom he believes is another firefly. This detail connects his character to the poem “Evangeline” by Henry Wadsworth Longfellow, which is associated with Louisiana and Acadian culture. Ray’s name is also a nod to musician Ray Charles.
A common mix-up is confusing Ray with Louis, the trumpet-playing alligator, or Mama Odie, the voodoo practitioner. Ray ultimately dies while helping Tiana and Naveen, and the film presents his spirit as joining Evangeline among the stars.
