Throughout this episode, Joe blows into the wrong end of the kazoo.
When Joe sings the song that is the answer to Blue's Clues, he sings all of the quarter notes as eighth notes.
Blue: I do wonder what you are. What are you, Little Star?
Macy: (singing) If you're feeling kinda crazy / like a wind-blown daisy / Do the Daisy.
Side Table Drawer: Today, you're going to find musical clues and then you can play them on your handy-dandy kazoo.
Toni: I've been practicing my singing for a long time.
Joe: Well, thank you for singing.
Toni: Hey Saturn, nice rings.
India.Arie, Toni Braxton, Macy Gray and They Might Be Giants receive a combined Featuring credit for their appearances. Brandy Panfili is credited as Brandi Panfili and T.J. Stannton is credited as TJ Stanton.
Oddly enough, Patrick Van Wagenen is on-board as Slippery in this episode, even though earlier in the sixth season, he was voiced by Sean Hanley. This might have to do with the production order.
The only time, so far, that the game of Blue's Clues is played without using the notebook.

Mr. Salt: (reading title off) Bluestock!
A reference to Woodstock, a huge concert in the 1960's that featured famous artists of the day.
