The Smurfalator is an invention that Gargamel created in The Smurfs 2 that is located in an underground laboratory beneath the hotel that the evil wizard and his cat Azrael were staying in in Paris. Its main purpose is to extract Smurf essence from the Smurfs in order to give Gargamel enough magical power for world domination and destruction of the Smurfs.
In the movie, Papa Smurf, Clumsy, Grouchy, and Vanity were the first to discover this invention when they were inside Gargamel's hotel room looking for Smurfette. Later on, when Vexy and Hackus were transformed into Smurfs, Gargamel put them as well as Smurfette and the other four Smurfs into the Smurfalator to extract Smurf essence from them. The invention was destroyed by Patrick Winslow and Victor Doyle when they entered Gargamel's underground laboratory to rescue the Smurfs.
