For more quotes, see the episode's transcript

Stuffy: This is so cool. Robot Ray takes the day off, and we get to do his job. So, uh, what's his job again?
Hallie: Keeping a keen eye out for toys in trouble. You just need to watch the monitors. Got it?
Stuffy: Yeah, got it.
Hallie: If you need anything, I'll be a hippo's hop away. And don't forget, Stuffy. Pay attention!
Stuffy: I'm sorry. What was that? Oh, yes, right. Pay attention.
Hallie: Mm-hmm.

Tracy: We're the triceratops train, and I'm the leader, that's right, the leader. Head honcho, triceratops in charge. Big cheddar.
Stuffy: Wow, you have a lot of jobs.
Tracy: Just one, but it's very important. I pull the triceratops train. It's what I do.

Doc: I won't know what's wrong with you until I run some tests.
Hallie: Which one, Doc? Battery test? Bounce test, balance test?
Stuffy: Or my personal favorite, the belly button test. (Pokes belly button and giggles) Okay, it's not really a test. I just like poking my belly button. (Pokes belly button) Oh, belly button. (Everyone giggling)

Doc: So now that I know you're okay, I have to ask. What gave you the idea to race around with Ricardo?!
Trina: Actually, it was Tracy's idea. She said we needed a new leader, because she couldn't be fixed.
Doc: Well, that's strange.
