In the game introduction, the troll king grabs Rosella by her wrist. In the beginning of Chapter Two, he pulls her into the room by her dress.
Valanice tears her dress on a cactus and takes the piece of cloth that tore off. Afterwards the dress is intact.
The black cat tells Valanice to seek aid from the Faerie Folk of Etheria, but does not mention any specific names. When Valanice visits the Fates, she tells them she must see Oberon and Titania, although she was never told to look specifically for them.
In the fourth game King's Quest IV: The Perils of Rosella (1988) Edgar's eyes are blue. In this game his eyes are black.
When Rosella enters the Faux Shop in Chapter Four, Ersatz the turtle tells her that he met Valanice. When Valanice asks him in Chapter Five if he saw Rosella, he says he did not.
Edgar wears medieval European garments, while his parents' clothes are ancient Greek.
The gate of Falderal has no hinges.
King Graham is listed in the game credits, but his character does not appear in the game.
During the song "A land beyond dreams", Rosella's both hands only have four fingers.
Sometimes Rosella speaks in Valanice's voice, and vice-versa.
