So should it look something like this?

By our gates
Over the mountain
Once lived a sandwich
With ham.
He wants
To go for a walk,
On grass-ants
To fall
And to lure him to himself
On an outing
rosy-cheeked butter
roll
But tea cup in sadness,
knocking and jingling, cries out:
“Sandwich,
Unorthodox,
Don’t go out of the gate,
But go –
You’ll end up in Fluffy’s mouth!
Fluffy’s mouth,
Fluffy’s mouth,
Fluffy’s mouth
You’ll end up in!”
