- Princess Flug's way of communicating is similar to how Petrie from The Land Before Time speaks.
- Her voice actress also voices True from True & The Rainbow Kingdom.
- Her snug is a bedroom hidden behind a crown-shaped door in the lobby.
- Like Harriet Bouffant, she appears like she might wear lipstick, although neither have been seen putting it on so it might just be their natural appearances.
- As of season 2, Princess Flug's only known relative is Flugtilda, Princess Flugs twin cousin from season 1's "Cousin Flugtilda".
