This is the tale of the very Who-beast
carved by the Grinch for the Whoville feast.
The creature in question was a Gǝzu
that grazed up high in the grassy puffoo.
She lived with others in a sizable herd
nuzzling her family without any words.
When moving en masse, the ground would thunder.
So, standing apart presented a blunder.
Aloof in pink grass, delicious to chew,
one day she was ambushed by hunting Whos.
Thus, blushing grass on the eve of the fête
led to the Who-beast garnished on a plate.
