On getting a Snickers

I love getting snacks from vending machines, because your change comes out refrigerated, coins like little metal ice cubes. They feel icy cold but dry in your pocket. It made me think of a song which my mother used to sing to me when I was little:

"Dogs' eggs and frogs' legs
And old broken clothes pegs
Fat cats in elf hats
And pictures of fruit bats
Berries and ferries and knobbly knees
These are all thinkings that occupy me
Notches and crutches
And things nicked from churches
Nodules and toggles and kittens in holdalls
Seagulls and beagles and ferrets on leashes
These are all things that I put in my quiches.
When the pork chops, when the bus stops, when clown babies crowd your mind,
When the moon lands, when the brass bands, you will be sure to find...
Lupins and moomins and logs all a'fluming
Vandals in sandals and Chief Montezuma
Robots and reef knots and snails on skates
Remember these things and you'll never be late!"

I've never quite been able to work out what she was getting at.
