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.
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.
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.
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!".
