Except they didn't say that. What the hell is "Where's Wally"? Are they trying to avoid trademark infringement or something?
Outside the US it's Wally, not Waldo.
Where's Wally? is a famous British series of picture books that are used to play a game of spotting a certain character named Wally. They are published in many countries around the world and in two of them, the US and Canada, I think, Wally was renamed Waldo.
