"We...Will See"

In the final scene of "The Butter Battle Book", just as Grandpa Yook is about to drop his Big-Boy Boomeroo, his rival Van Itch appears holding one as well. The Yook grandson can only ask who will drop theirs first, with his grandpa telling him to "be patient", the story ending with the implication that the Yooks and Zooks will experience total destruction.
