My mum used to sing - or maybe just recite - I cannot remember. She died many years ago. The words were

There once was a rabbit developed the habit of twitching the end of his nose
His sisters and brothers and various others all (noted) the way that it goes...
...
It ends ...
Now all the world over where rabbits eat clover ...

Does anyone recognise this and can they supply me with the comlete text?

Pleeeeeeeeease
