Oops - forgot my other favorite -
Down by the meadow in the iddy biddy pool
Swam three little fishies and a momma fishie too
"Swim," said the momma fishie, "Swim if you can,"
So they swam and they swam, right over the dam.
Boop, boop, diddum, daddum, waddum, choo!
Boop, boop, diddum, daddum, waddum, choo!
Boop, boop, diddum, daddum, waddum, choo, and they swam and they swam right over the dam
