The Magical Moo

I once knew a cow with a magical moo,
She mooed every morning for something to do.

She mooed on a Monday, and what do you think?
The milk that she gave was a strawberry pink.

She mooed on a Tuesday, but not very loud,
And silvery linings filled every cloud.

She mooed on a Wednesday, and soon all around
The daisies all danced to that magical sound.

She mooed on a Thursday, and then by and by
Some pigs were seen flying way up in the sky.

She mooed on a Friday, a little forlorn,
Then cheered us all up with a honk on her horn.

She mooed on a weekend, and what happened next?
She vanished completely, I’m truly perplexed!
