In this episode, the Dancey Dance is in the style of "Having A Party".
When everyone comes out and yells, "Surprise, Brobee!" a drumroll plays.
This is the first time DJ Lance Rock says "Then...", instead of "Finally...".
When Brobee blows out one candle at a time, a noisemaker plays and the pitch increases.
After the blowing of one candle at a time, counting happens.
After DJ Lance Rock says "Let's remember all the fun things we did today!", the gang doesn't cheer.
After DJ Lance Rock says "All right! What a special birthday day.", the gang doesn't also cheer.
When everyone yells, "Surprise, Brobee!" the black bat doesn't come out.
In the exterior of Brobee's birthday party, where Room is laughing as balloons and confetti come out of her mouth, we don't see Gooble and Brobee Cake, we only see Parker Jacobs in a different direction.
