Bob Iger and Josh D'Amaro better use the things found in the time capsule as an excuse to properly expand and enhance the park. Nobody wants the urban jungle that is Zootopia in a natural jungle. (Moana land could work in Animal Kingdom as long as that area has animal encounters, mainly sea animals from the South Pacific.)
Said time capsule could maybe convince Iger and D'Amaro to revive Beastly Kingdom, even if it’s in a different way from the original plans in the 90s. Oh, and said capsule could also help bring a South America and Australia land to fruition.
