The Fairly OddParents S05E26 - What's the Difference?

Mark seeks Timmy's help after his fake-i-fier malfunctions and his evil fiancée Princess Mandie tracks him down to Dimmsdale Elementary School. To hide Mark, Timmy wishes the school into a puzzle book, which causes Cosmo and Wanda to lose their wands in the puzzle. As Mandie will turn Dimmsdale into a crater if she does not find Mark, Timmy must find the wands and wish everything back to normal.
