Stuffy: I guess it's time for your checkup.
Toys: Time for your checkup, time for your checkup!
Doc: I'm gonna check your ears--
Stuffy: (humming the song)
Doc: You are ready for your checkup now, aren't you?
Star Blazer Zero: Yes, Doc. I need you to find out what's wrong with me.
Doc: Good, now the Doc is in.

Doc: Stuffy, could you get those cards?
Stuffy: You got it, Doc! Brave dragon on duty! Wha, whoo, ooooohhhh!!!
Star Blazer Zero: I gotcha. (Grabs Stuffy by his tail)
Stuffy: Here's the cards. Some of 'em. Heh.

Doc: Can you see what this is a picture of?
Star Blazer Zero: Why, yes. That is pretty yellow petal plant.
Lambie: I'd have said it was a sunflower.
Star Blazer Zero: A flower that comes from the sun? Ka-Zow!
Doc: They don't come from the sun. (Giggles) It's just the name of a flower that grows on our planet.

Doc: On Earth, these are frogs. They're really quite harmless.
Chilly: Yeah, they wouldn't hurt a fly.
Stuffy: Frogs eat flies.
Chilly: I'm glad I am not a fly.


  • Diagnosis: Helmet-no-fit-osis
  • After the song "Time for Your Checkup" ended, Stuffy was still humming along to it both times. The first time when only a few lines were sung before Doc stopped the song to ask Star Blazer Zero if he was ready for a checkup. The second time, it was right after the song ended for real.
  • Daisy looks ordinary in the episode.
  • This is the first time Chilly and Star Blazer Zero appear together.
  • This is the second time Star Blazer Zero got a bad case.
