There is a statement in the closing credits: "No digital cats were harmed in the making of this picture."
SPOILER: Part of the closing credits are seen in the waterfall portal, from which appear photographs of the Winslows and the Smurfs after their encounter: the Winslows are seen with their newborn son Blue, and Smurf Village is rebuilt to resemble New York City.
At the end of the closing credits, a Smurf is seen reclining on the upper left of the Columbia Pictures logo, smiling and waving to the audience.
SPOILER: There is a scene in the closing credits: Gargamel and Azrael, stuck in New York, moan their fate. Gargamel then notices the viewer and attacks the camera with his wand.
The closing credits are set against a blue background, and are filled with Smurfs carrying out gags.
The opening title is formed from Smurf essence.
