Joe had to be outside for almost the entire episode because he was not supposed to go into the kitchen because they were having a surprise party for him in that room.
This is the only time where different characters sing about how to play Blue's Clues.
Mr. Salt, Tickety and Periwinkle sit in the thinking chair for the demo of the game.
Tickety, Slippery and Periwinkle are the characters that played Blue's Clues with Sidetable Drawer handing them the notebook to let them draw the clues. Tickety drew the first clue (tape), Slippery drew the second (Joe's present) and Periwinkle drew the last (wrapping paper).
Slippery had to ask what the first clue was because he was not around to see who drew it.
"The Birthday Song" from "Blue's Birthday" was sung in this episode, but the lyrics were changed to: "Everybody play, it's Joe's Special Day, Happy Birthday!" because it was Joe's Birthday in this episode.
This episode is often considered the Joe version of Blue's Birthday only it is Joe's Birthday.
This is the first time Joe was seen in a blue shirt.
This is one of the only two episodes where someone other than the host plays Blue's Clues. The second will be in Joe's Clues.
This episode is speculated to have been taped on Donovan Patton (Joe's actor)'s birthday, March 1.
