Bronty: Cousin Stuffy put cardboard wings and pointy things on me so I could be an honorary dragon. Oh, how do I look? Do I look good?
Doc: You look great, Bronty. Just like a real dragon.
Bronty: Oh, you hear that? I look like a real dragon. Just like a real dragon.
Dragon Bot: Then why don't you give a mighty roar to lead our dragon attack?
Bronty: Oh, okay, okay, okay. Roar.
Stuffy: Uh, I'll take it. Dragon attack!
Lenny: Ooh, that was so great! We did it. We knocked down the fort.
Stuffy: You were awesome Len-ster. High hose.
Lenny: I always wanted to see what it felt like to be a dragon.
Stuffy: Yeah, I know. Being a dragon's pretty awesome.
Stuffy: (After Lenny comes out from the feather pile) Lenny. You scared me. I mean, you woulda, if I wasn't so brave.
Stuffy: But can you take on four dragons?
Lenny: Four dragons? I only see three.
Bronty: Nope, there's four.
Dragon Bot: Stuffy the mighty, Dragon Bot the roboty, Bronty the brave...
Stuffy: And Lenny the featherless, fire-breathing, fire truck.
Lenny: Does this mean, what I think it means?
Stuffy: Lenny, you are an honorary dragon.

- When the Blanket Fort is knocked over as part of a game, Professor Hootsburgh states to Sir Kirby that "We can rebuild it. We have the technology. Better than before." This is a reference to the series "The Six Million Dollar Man".
- This is the second time Lenny got a bad case.
- Lenny sings "I Feel Better" for the first time.
- Stuffy, Lambie, and Professor Hootsburgh got wet after being squirt by Lenny during the song "Can't Stop the Giggles". But in the next scene, they were dry again. The same goes for Hallie later on.
- This is the second time Stuffy got wet. The first time was in "Slip 'N Slide".
- This is the first time Lambie, Hallie and Professor Hootsburgh got wet.
- Chilly was the only stuffed animal who didn't get wet.
