Following your dreams and getting by with a little help from your friends are the two big take-aways. And Kermit insists it's better to face a bully than run away. Additional themes include integrity, perseverance, and teamwork.
Plenty of slapstick, including Miss Piggy's famous martial-arts skills. Kermit is also chased across the country by men with guns, and one particularly menacing-looking frog assassin, and his brains are almost scrambled by electricity so that he can be controlled by the owner of a frog legs restaurant (there's lots of frog leg imagery, too, that makes Kermit sick to his stomach). Miss Piggy is kidnapped, and Kermit and Miss Piggy are tied up and held at gunpoint. Shots are fired at Fozzie on stage, one car lands on top of another; Kermit is twirled around a ceiling fan and falls off; one Muppet really likes dynamite; and a giant Animal Muppet frightens away the bad guys.
Miss Piggy and Kermit hug and kiss. In a Miss Piggy dream sequence, she and Kermit frolic in the park; you see Miss Piggy on top, then Kermit. Animal shouts, "Woman, woman!"
Schwinn bicycles get a punny mention, and there's a Studebaker car and Variety magazine.
Drinking, Drugs & Smoking
Characters in bars and the Hollywood agent smoke cigars. Kermit and Miss Piggy drink wine with straws and a woman asks Kermit to buy her a drink. Ralph the Dog sings about having a couple of beers before bed.
