Hagnes is one of The Three Hags in Super Paper Mario.
Favor[]
Hagnes's favor is only that you listen to her. She tells a story of her past love life. She says she competed with Queen Jaydes for Grambi's heart. After she is done, the only reward the player gets is a thank-you. It doesn't do any good to the player.
Complaint[]
When the player says no to listening to her she, unlikeHagitha or Hagra, doesn't blame anything. She says when she was young, she was like that too.
