Gotta love the 80s, eh? "Punch", of "Punch and Judy" fame, advises the kid audience to never trust strangers, demonstrating this, by not climbing into the Crocodile's motor. The West country voiced policeman warns the children if knowing where they are, when alone, and not to take rides from strangers, otherwise your a "naughty, naughty, naughty man"! The Crocodile sounds a bit like the other puppet croc from CITV's late-80s show "Round the Bend".The PIF was made in 1980, and does, even then seems a bit dated to be using such a politically incorrect technique. But that's why we love that age!
