While Steve skidoos in the frame, he doesn't sing "Blue Skidoo, We Can Too." Instead, he sings "Let's Skidoo, Don't Tell Blue".
There was a two-disc PC game based on this episode released by Humongous Entertainment as Blue's Birthday Adventure.
This is the last time where Steve skidoos into the Present Store.
On the VHS Version, four celebrities who wished Blue a happy birthday are:
Gloria Estefan.
Tia and Tamera Mowry.
Amanda Bynes and Michelle Trachtenberg.
Even though Rosie O'Donnell didn't appear in the VHS Version, she did so appear in the TV and DVD version.
Original airings in 1998 also featured celebrity birthday wishes from Whoopi Goldberg, Melissa Joan Hart, Spice Girls, and the cast of The Wubbulous World of Dr. Seuss. Those celebrity appearances were taken out of subsequent airings, as well as the VHS version, but they were also used and kept in the Kevin and Durate versions.
Blue did not skidoo into the Present Store.
This is the first time in Season 2 and in the series where Steve skidoos alone.
This marks the last time the "Play Blue's Clues" footage from Magenta Comes Over is used.
This is the third episode to use the brass instruments in the song.
This is the last episode where Steve's off-screen friends (the viewers) sing out Blue's Clues in the demo theme song.
This is the only episode that did not use the hoomans in the Nick Jr. still logo (With the closing credits music ends throughout and short 1998 copyright info.)
On the 2006 DVD release of Blue's Biggest Stories (The TV version of this episode was used,) the logo got plastered by the Nick Jr. Productions and Nickelodeon logos (The later got the 2006 copyright info.)
Because of Jeffrey Fernandez's hair styling for Steve Burns, this is the first time Steve's hair was shorter, not counting the theme song from the episodes.
In the Steve and Duarte verisons, the credits are shown in the birthday banner at the ending of this episode as the "So Long Song" is being sung. This is also the first time this happens.
In the Kevin version, the credits are shown after Kevin blows his party noise maker in the same white page as any other credits.
"Blue's Birthday" is available on the VHS of the same name. The VHS contains extended material that cannot be seen on television.
This is the fourth time the "No, a Clue" phrase is heard.
This episode introduces Blue's pet turtle, Turquoise, who will appear in many future episodes.
This is the first time the program had featured celebrity guests, but they will appear many times in the future, either as themselves, or as character voices.
In the mail segment in the TV version of Blue's Birthday, Rosie O'Donnell was the last celebrity shown in the letter. Rosie's birthday wish from Blue was cut in the VHS extended version of this episode due to copyright issues with Warner Bros.
This is the second episode to use the original cheers and applause sound effect.
This marks the first episode to feature a different variant of the Handy Dandy Notebook. This also happens in later episodes.
Out of all the episodes that feature a different variant of the notebook before Love Day, this the only episode in where Blue pulls out the notebook's variant during the theme song. Unlike the other episodes, Blue pulls out the normal notebook.
Some of the toys at the present store include Gingerbread Boy and Tickety Tock's presents, as well as several toys from the house from previous episodes (like the Toy Giraffe from Blue's Senses).
Other things found in the present store (specifically on the shelf near Cash Register) include birthday cards 3 bubble bottles of different colors (Slippery Soap got the pink one as his present for Blue).
This is the only time where one of the main characters (Except for Blue) has skidooed into the real world.
The intro of the episode from the VHS version is the same as the kids are heard at the beginning of the TV version.
This is the first episode to feature the color green as a clue. It is followed by Dress Up Day.
In The Kevin Version Of The Letter Segment, The Wubbulous World Of Dr. Seuss Was In It & The Cat In The Hat & All Of His Friends Wished Blue a Happy Birthday. Here’s The Link To See The Birthday Letter From The Kevin Version https://youtu.be/zNDdsmTYOFE
Goofs
In the opening sequence, the viewers don't shout, "There she is!", only one viewer says, "Right there."
Captioning for Blue's barking throughout the episode reads things like "bowwow," which is not normal practice.
Normally, it just says "(Blue barking)" or something to that effect.
In the scene where Steve leaves the kitchen to go outside, on the bottom of the screen is a black strip, and when Blue jumps and appears in the window, you can see her bottom half missing before and after she jumps.
Before Mr. Salt and Mrs. Pepper bring the cupcakes, the latter was seen at the left side of the screen.
When Steve says "Okay." The Boom Mic is seen on top of screen.
When Steve comes a little close to turquoise, part of his neck is cut off.
In the ending/closing credits, Angela Santomero is credited as Angela C. Santomero.
