Newly engaged, Fru Fru kicks off wedding planning with enthusiasm and flourish—at least until her scene-stealing cousin Tru Tru arrives to assume the role of Shrew of Honor. A battle for the spotlight ensues until a close call with a giant donut reveals that for better or worse, no one knows you better than family.

A touching tale about the powerful arctic shrew known as Mr. Big revisits Fru Fru's big day when he delivers a revelatory father-of-the-bride speech. Taking guests back in time to his days as Mr. Small, a new immigrant to Zootopia, he imparts the wisdom he gained then about the importance of friends, family and community.
