And near the forest stood a rose,
now spotted by two unicorns.
As rose observed the creatures pose
it flashed in anger all its thorns.

The unicorns began to sing
and spread, bilaterally, a wing.
The king of flowers, known as rose
said 'what a weird and ugly nose! '

Both unicorns got raging mad
which made the situation bad.
Attacking quickly now the rose,
they soon collided, nose on nose.

And in the shuffle both felt faint
(you see, all roses have a saint) ,
and neither did regain their spark
until the forest was too dark.

Try as it might, a unicorn
can't see in darkness. It is born
nightblind (it lacks the carotene) .
The two gave up and left the scene.
