The characters provide strong messages about teamwork and selflessness -- knowing those you love well enough to recognize when something is wrong or someone needs help. The Muppets have really strong friendships, and they would do anything to rescue Kermit, who in turn, loves all of his Muppet pals.
Kermit is mistakenly arrested and thrown in the Gulag, where conditions are tough and the guards all have weapons, mostly big guns. Constantine, who can be very menacing, fights with the armed guards (kicking and hitting) as he escapes the Gulag, whereas Kermit tries to escape via the toilet. Constantine sets off loud explosions, but no one is shown getting hurt. Nadya tasers a prisoner, who's shown twitching from the shock. An item a character wears turns out to be an explosive device.
Muppets kiss; a woman kisses a picture of Kermit and clearly has a crush on him.
The words "butt," "idiot," and "stupid" are used a couple of times; some occasional swine humor is directed at Miss Piggy.
The Muppets have strong merchandising ties to toys, apparel, accessories, home decor, and -- of course -- their own programs and movies on DVD.
Drinking, Drugs & Smoking
Miss Piggy is offered a glass of champagne; another (adult) character has wine.
