@EMF: He did, but the suing thing wasn't that severe, though, but, Lady GaGa forced them to take off "The Moshi Dance" because it had parts of Bad Romance in it. Then the Underground Disco still had Peppyrazzi, but it was replaced with Baby Rox. Even Missions 1 and 5 were changed. The title of Mission 1 wasn't changed, but the egg hatched into Baby Rox instead of Lady Goo Goo. Mission 5's storyline and title was changed. Mission 5's title was changed to Pop Goes the Boo Boo, since Lady Goo Goo wasn't being promoted anymore. The storyline is based on how Lady Goo Goo's voice was lost, but Baby Rox took Lady Goo Goo's place in that mission. Baby Rox is in the Moshling Zoo (Moshi Members Only feature in the website) in the Secrets category, as #102, where Lady Goo Goo used to be. They might have to use Baby Rox and remake "The Moshi Dance" again.
