said hippo potty must

the chubby hippo eats much more
than his allotted share,
I candidly declare,

of fibrous roughage,
developing within a gross surplusage
that makes his lower tummy sore

eventu’ly he must make room
by light of nightly moon
(and that from womb to tomb)

and to do so, I trust,
indeed, from time to time
said hippo potty must.
