An interesting thing was found times ago, in Luigi's Mansion (2001) game was found among the textures a Daisy one, it was her artwork from Mario Tennis 64. Her texture was found between the painting textures and it was called "text", this could mean it was just a test for the painting textures or this mean Daisy was supposed to appear in this game? Nothing was confirmed... I've alredy added it on "Daisy appearences" check it out! If you sreach (o come cavolo si dice) "Luigi's Mansion Daisy" you can found the photo on the pictures and there's a site about it.
