Common Sense Note
Parents need to know that this is your typical fun Muppet entertainment with some big musical numbers mixed in. Violence is mostly slapstick -- lots of getting thrown from or in front of moving vehicles -- and there's some sexual innuendo that kids will probably miss. Of course, Kermit and Miss Piggy get to smooch once. They also have a glass of champagne at a restaurant.
Sexual
Content
A Kermit-Miss Piggy smooch and Nicky tries to kiss Miss Piggy. Plus some innuendo meant for adult laughs: Animal runs after the models shouting "woman, woman"; Gonzo claims he's photographing kneecaps when he's found in a dressing room; Miss Piggy throws a man into a lake yelling "get your filthy hands off me!"; Waldorf and Statler talk about bikini-clad models; and a man confesses he's out to dinner with a date other than his wife.
Violence
Mostly slapstick violence throughout. Gonzo falls or throws himself in front of cars a few times. Kermit, Fozzie, and Gonzo are thrown from planes and busses; Miss Piggy throws someone out of a truck and another man into a pond, and also uses her signature karate chopping moves. A Muppet is electrocuted (but OK), and a gun is pulled, threatening Kermit. A crazy Muppet cab driver crashes straight through the hotel. A mention that someone might get killed when all the Muppets start planning to thwart the jewel heist.
Language
A mention in the song about the Happiness Hotel that it's "gone to hell."
Social
Behavior
Fozzie tells the other Muppets they're stopping a jewel heist for "justice, freedom, and honesty." There's some bravery and friends stick together. It's very refreshing when the full-figured Miss Piggy hits the runway in a swimsuit to thunderous applause.
Consumerism
Quick mention of American Express.
Drugs / Tobacco /
Alcohol
Miss Piggy, Kermit, and Fozzie drink champagne at a fancy restaurant and one non-Muppet smokes a cigar.
