It's a Conspiracy!!![]
Daisy's secret alter ego is none other than Fawful himself! (Or maybe, er, herself?) The more you think about it, the more it seems true!
Evidence[]
The first recorded evidence that Daisy might be Fawful was in Toad Town in 1975, during the Yoshi's Island Scandal. She assumed most Toads would be gone, and changed into Fawful in front of a shocked Toad who was still around. All other recorded evidence was either lost or burned by Daisy. Or maybe they were used for Cheeseburger meat.
Belief Against[]
A lot of people disagree to this, and think Daisy is in no way really Fawful. They must have all said -SECTION EITHER LOST OR BURNED BY DAISY, OR POSSIBLY USED FOR CHEESEBURGER MEAT-, and that's how they believe that Daisy isn't Fawful. But the rumor still stands!
