How many challenges are there from Mr. Mxyzptlk in Superman Returns: The Videogame?

Between 5 and 14, gaming system pending. The Xbox and PS2 have the "Playable Bizarro" mini-games, which make five locations, but the Xbox 360 has an ADDITIONAL 9 "Fast Flyer" mini-games. And depending on what system you have, the Bizarro games will be in different locations. PS2/Xbox have them in the same places, but Xbox 360 has them in separate areas.
