You walk around the forest in the Mushroom Kingdom when you hear soft breaths coming from behind the trees... You see a little shed and decide to peek into it. No one's there fortunately but then you hear a soft whisper from behind

"Hello..~♡" you see a pretty ghost girl.... She has a little crown on her head and she blushes a bit "I'm Princess Boo...~♡" she holds out her trembling hand while holding her cheek with her other hand
