A frog and a mouse fall into an argument over a flower in this wordless modern classic, perfect for starting conversations with children about peace, conflict, warfare, and the importance of de-escalation. In this new edition of a wordless modern classic, a frog picks a beautiful flower. When a mouse sees him with it, his jealousy overcomes him, and he grabs it for himself. Then Frog's friends chase the mouse away. But before the frogs can celebrate, a counter-attack from Mouse's friends surprises them--and the conflict soon escalates into a full-blown war. When the dust finally clears, all either side can ask is: Why? With an afterword by children's literature expert Leonard S. Marcus, this seemingly simple book is an invaluable way to talk to young children about conflict and warfare.
