Sir Bumbleby, the tiny knight

Sir Bumbleby, the tiny knight
was only two inches in height;
his armour was made out of tin
and, for his sword, he had a pin
and a brass button for a shield
which, each day, he would bravely wield
fighting mice that were twice his size
and fire breathing dragonflies
to save his damsel in distress,
the lovely Daffodil princess.
