Will Smurfette Get ‘Naughty’ With Her Kidnappers in ‘The Smurfs 2?’ (Video)

Smurf nemesis Gargamel (and his cat) are still out to screw up the little blue guys' days in the sequel to the 2011 film

"Welcome to the party," says Gargamel (Hank Azaria) to open the new trailer for "The Smurfs 2."

In the sequel, Gargamel is out to make his own Smurfs — called the "Naughties " — and nothing can stop him, except maybe the Eiffel Tower.

In the trailer, Smurfette (Katy Perry) is kidnapped so Gargamel can learn the formula to create true blue Smurfs. But first his Naughties have to brainwash her with some adventure that Papa Smurf likely would not condone. Will Smurfette turn naughty? Or will the Smurfs save the day (again)?

Cue the rescue mission — in the form of Neil Patrick Harris.
