At one point the close-captioning reads that Blue is barking the "We are looking for Blue's Clues" song, but technically, she's actually barking "We are looking for Joe's Clues."
Joe: (as duck) I hope you enjoyed the Joe Show. Quack.
Joe: (as duck) I am the duck / I love to quack / But Little Red has my snack...
Joe: (singing) It's the Joe Show / It's the Joe Show / It's a show for you / It's a show for Blue / It's a show about the wacky, quacky things I do.
Joe: (taunting) Where am I? I got your clue!
Mailbox: You're gonna skidoo into your letter?
Blue: (barks confirmation)
Mailbox: Amazing! I mean incredible! I mean wahoo!
Tickety: Come on! Follow that duck!
Joe: (dressed as a duck) I gave your clue to a friend of mine. Quack.
Joe: Well, today, I'm going to leave the clues and you and Blue will have to find them. What do you think of that?
Joe: Do you really really really really really wanna know what it is?
Joe: Well, I'm not going to tell you.
Joe: Guess what. I have a big surprise for you and Blue.

This is only the second time that the show has broke from custom in regard to the show's hallmark game. The first time was in "Joe's Surprise Party," when the characters all played the game.
Joe is wearing an orange shirt in this episode, but changes into a green shirt when dressed as Little Red Riding Hood and wears a yellow shirt for his duck guise.
Mailtime Segment: Joe suggests that Blue and us get the mail today, so Blue barks the "Here's the Mail" song and we sing along. Mailbox tells us that the second clue is in the letter, so we and Blue actually decide to skidoo inside to get it.
