It's Hallie's birthday and Doc and the gang throw a surprise party in her honor.
Three years ago, Doc's mother gave Hallie to Doc and she uses the day as Hallie's birthday. Doc and the toys want to do something special for Hallie, so they decide to plan a surprise party for her. But they'll have to bring all the supplies into the clinic without Hallie seeing, so Doc comes up with a plan. She tells everyone that Stuffy and Lambie will pretend to be nurses while everyone else will pretend to be sick.

Doc: (about Hallie) If I know that hippo, and I do, I know there's two things she likes, parties and surprises.
Lambie: (gasp) Sounds like we should throw her-
Stuffy, Lambie and Chilly: A surprise party!
Doc: Okay, everybody. We have to sneak all the decorations and the cupcake into the checkup room without Hallie seeing us.
Chilly: So what's the plan?
Doc: Lambie and Stuffy will pretend to be nurses. And I'm gonna need you guys to pretend you're sick.
Chilly: I'll try, but I don't know if I can pull it off.
