This is the first Christmas episode to feature Zooli.
The Christmas-hating Humbug is a reference to the quote Bah Humbug said by Ebenezer Scrooge in Charles Dickens classic story A Christmas Carol.
This will be the third Christmas special on Nick Jr. in 2020 and the only Christmas special to release the same day (Friday 4th December) following Blue's Clues and You! with the special Blue's Night Before Christmas and Ryan's Mystery Playdate with the special Ryan's Christmas Time Special.
The Humbug is inspired by an actual bug, due to his appearance and name "Humbug".
This is the second episode to be winter themed since Ocean Patrol!.
This Second Episode has Molly and Gil hold hands.
After this episode has aired, there will be a 48-day hiatus until the premiere of The Mighty, Untidy Titans!, which will be the first episode of 2021.
Ironically, these episodes premiered at the beginning and end of the year. Ocean Patrol! premiered at the beginning of the year in January, and this episode premiered at the end of the year in December.
The Little Fish and Goby dressed up as elves throughout the whole episode
Molly and Gil's skit room does not appear for the fifth and final time.
This is the first Season 5 episode to exclude a Molly & Gil sketch at the beginning, the first S5 episode not to feature the Outside song, and the first time since Bubble Puppy's Fin-tastic Fairy Tale! all the way back in 2012 where the story is read from an actual book.
