Frog is a creature who lives in the forest. The story is framed by Frog’s narration—he opens the play by describing the shadow of Ti-Jean in the moon, once he has beaten the Devil and been placed in the skies by God. All three brothers cross paths with Frog on their way to meet the Devil for the challenge. The three brothers’ different approaches to interacting with Frog demonstrate their different understandings of God—while all three boys have been taught to respect all of God’s creatures, only Ti-Jean treats Frog with respect, while Gros Jean and Mi-Jean insult the animal. This suggests that only Ti-Jean truly has respect for all of God’s creatures, and indeed, he is rewarded for his faith: Frog gives Ti-Jean the advice he needs to recognize the Old Man as the Devil in disguise
