There is no Shadow segment in this episode.
This episode features three songs --- "The Mumble Mambo," "Go With an Open Mind" and "The Firefighter's Cha-Cha-Cha," which is a send-up of "The Bear Cha-Cha-Cha" heard in many episodes. It features the same music and many of the same lines, but others are changed to be firefighter-related.
Harry and Mama Duck attend the Firefighter's Ball, although neither have any lines in this episode.
Luna: Life is full of surprises, Bear. All the times I've looked down on the Earth, I've never seen the same picture twice. It's amazing. But the one thing you can always expect is the unexpected.
Luna: And once you accept that, then you're ready fand willing for life to surprise you.
Bear: That was without a doubt the best firefighter's ball Woodland Valley has ever had. Of course, this was the only firefighter ball Woodland Valley's ever hard. I can't wait to tell Luna all about it. Come on, let's go tell her.
Tutter: It's raining Roquefort, Bear. Roquefort!
Bear: Roquefort? Tutter, what's wrong?
Tutter: Well, I just found out that there's this new dance and all the mice at the school are gonna be diong it at the ball, Bear. Tonight! And I don't know it.
Bear: Wow. Everybody sure has a lot of expectations about tonight's Firefighter's Ball. Say, do you an expectation is? Expectation. It's a big word, isn't it? Well, an expectation is something you think or expect to happen in the future.
