- This is the second time in a blooper where the characters only talk through real voices, the first being Christmas 2013: The 12 Idiots of Christmas.
- However, due to criticism from many fans, SMG4 decided to not generalize that in his future bloopers and to come back to captions and voice clips.
- Since SMG4 is discontinuing real voices, this video would be the only video in which the SMG4 intro is read out loud to the viewer.
- This is the first video to have an updated model of Luigi (his previous appearances were recolored palettes of Mario).
