There are millions of me. I am very small but when moving fast I am deadly.
As round as an apple. As deep as a cup. All the king's horses can't pull it up.
Stealthy as a shadow in the dead of night, cunning but affectionate if given a bite. Never owned but often loved. At my sport considered cruel, but that's because you never know me at all.
When the creeper passes, all the grass kneels
What is weightless but takes two people to hold it?
What animal dwells in water and best known for its work ethic?
