The Blue Princess is one of the four princesses found throughout the game Castle Crashers.
She is captured by the Barbarians, and then sold to the Frost King. She wears a blue gown, a blue hat, and has blue eyes.. When the Frost King is defeated, she later appears at the celebration, where she seems impressed by a Thief's archery skills.
- She is the same color as the Blue Knight.
- She is the third princess to be rescued.
- Like the other princesses (Except for the Orange one) she resembles a member of the Powerpuff Girls: Bubbles
- It may be by chance, but the Frost King imprisoned her and they're both wearing blue and have relation with ice (she is the same color as the Blue Knight who has ice magic.).
