The decorations and the stuffed puppy that the viewer picked for Blue's present was rainbow-colored instead of blue with spots, just like Blue herself.
Josh blows his party blower at the viewer after he tells the viewer that he loves birthdays.
Josh winks 39 times in this episode.
Josh makes kissing noises while pretending to be a fish for the fishes. However, in a promo for this episode, he kissed his own giraffe balloon that he made.
In a promo for this episode, he did an impression of Blue while revealing a Blue’s ears balloon party hat.
The part where the missing balloon and napkin were fixed were absent.
In the original episode, the first clue (the color green was represented by a green non-sentient but mobile paint drop. In the reboot episode, it was represented by a mere green paint splat.
Many of the Present Store toys look different.
In the original episode, Steve refers to the plush animals as "adorable little toys". In the reboot, Josh refers to them as "adorable little stuffies".
There were more pets at the Present Store beside Turquoise (who is the only turtle in the store): a blue and purple chameleon, and a pair of fish. Josh refers to the fishes as “cute fishies”.
The tank that the fish were in represented as the second clue (a tank). In the original episode, the tank representing the second clue was an empty one in the kitchen.
The fact that the second clue is in the present store does not make sense, because Blue did not and is not supposed to go in the present store or her presents will be spoiled (unless she skidooed and put the paw print there a while before Josh skidooed there).
In the original episode, after Steve asks the viewers who's favorite game of musical chairs is which was Mailbox, the Mailtime Song begins. In the reboot, after Josh skidoos out of the picture frame, the Mailtime Song begins.
Josh still has a present in his hands while he sings the Mailtime Song.
This episode also took place before "Laugh with Blue" because Turquoise was seen in the bedroom bookshelf.
This episode also takes place after “Meet Josh!” because, after Blue put her pawprint on the screen, Josh said “I know what that means!”, referring to learning how to play in the said episode.
Not counting the 2002 update of Blue's Clues Live!: Blue's Birthday Party, this is the first time Joe celebrates Blue's birthday. This is ironic because Joe had a birthday in "Joe's Surprise Party" in the original Blue's Clues series.
This is the second time Alexa PenaVega appeared in a form of Blue's Clues media, she previously appeared in a promo for the Blue's Clues special "100th Episode Celebration".
This is the second episode that doesn't follow the formula "[Subject] with Blue/[Character]" after "Meet Josh!".
