After getting a kid's balloon back, Skipper mentions something about The Big One. He explains he has been waiting for it to come for months and he hid some plans in a remote area of the zoo for when the big one comes. But it is revealed that they are building a children's zoo on the spot he hid the plans, so now they try to get the plans before The Big One Comes. But Skipper then starts acting like a news reporter. Can Skipper stop acting like a reporter, and can they get the plans in time before the Big One comes?

When the zoo closes for the Christmas holiday, the animals gather to begin work on Kidsmas, their annual holiday festivities mainly designed to delight the younger animals. Each animal is assigned a Kidsmas preparation task to perform, but Julien, desiring a different one, rearranges each animals' task.
