Similar too, but we said
"Ip dip dip
My little ship
Sails on the water
Like a cup and saucer
You are not it"

My kids )Leicestershire) use something like your second one Snuffy, but I think it goes
"Ibble obble chocolate bobble
Ibble obble out
Turn your petticoat inside out.
Not because it's dirty,
Not because it's clean
O-U-T spells out and out you must go"
