The team zaps into a musical fairy-tale land where they must sing whatever they say and their true feelings come out in song.
- This episode was released early on WATCH Disney XD.
- It's revealed that Penn sleeps with a teddy bear and Rippen sleeps with a poodle named Freddy.
- Boone creates a clay model of Pigoilet, a creation which he drew before in "Cereal Criminals".
- This episode marks the first time the main heroes and villains swap genders for a mission.
- This is also the first episode to be a musical, but more like an opera due to most of the dialogue being in song.
- The use of the adjectival phrase "most fair" in the title after the noun "princess" which it modifies, rather than before (as in modern English usage), hearkens back to older varieties of English in which such inversions were common, particularly in poetical phrases such as "maiden most fair" and "lady most fair."
