Doc: O Stuffy-o, o Stuffy-o, wherefore art thou Stuffy-o.
Stuffy: But soft, what light through yonder window breaks? It is the east, and Doc McStuffins is the sun. (Doc giggles)
Lambie: To baa, or not to baa, that is the question.
Professor Hootsburgh: Oh, I do love a good play.
Chilly: All the world's a stage, and all the toys and kids are merely players. (Everyone laughs)
Professor Hootsburgh: Well said, Chilly.

Doc: Looking at a patients symptoms and making a proper diagnosis is a very important part of being a doctor.
Stuffy: I don't think we have this diagnosis thing down yet.
Lambie: We wanna become doctors, like Doc.
Doc: It takes a lot of practice, but you'll get it. I know you will.
Chilly: Yeah, but what if we don't get it?
Doc: Don't worry. If you keep trying and keep practicing I know you can do it. Just follow me around the hospital today. You can watch and see how I make my diagnoses.
Stuffy: That is a great idea.

Lambie: You wanna head to Peaches Pie's Tea Party Palace? Maybe a tea party will help us feel better.
Chilly: Might as well.
Stuffy: Sure.

Stuffy: Guys, something might be wrong with Peaches Pie. We are med students, and we have to make a diagnosis.
Lambie: Stuffy's right.
Stuffy: Let's remember what Doc taught us. We have to ask good questions and look for clues.
Chilly: Do you have any symptoms besides coughing?
Peaches Pie: I have a really scratchy feeling in my throat. (Coughs)
Lambie: And how long have you been coughing?
Peaches Pie: Ever since Gloria Gorilla came in. (Cough) I remember. She said she wanted to cool down with some tea... (cough) after she was making sand castles at Sand Box Beach.
Chilly: Gloria was all covered in sand when she came to the hospital.
Lambie: What if the sand from Gloria's fur got in Peaches Pie throat?
Stuffy: And that's what's making her cough.


  • Diagnoses: Sand Scratchies, The Scratchy Sand Coughy-coughs
  • The play Doc and the toys put on in the beginning of the episode was a reference to Shakespeare and his plays:
    • Doc and Stuffy's lines are a reference to "Romeo and Juliet".
    • Lambie's line is a reference to "Hamlet".
    • Chilly's line is a reference to the monologue that begins "As You Like It". Chilly is also wearing the same ruffled collar that Shakespeare wore.
