Pops(es s?)

While eating some delicious Pops cereal, I accidentally spilled one of the morsels of the cereal on the floor. I said,

"Oh, I dropped a Pop."

But that isn't right, is it? The cereal name is Pops. So if I dropped one, would I be dropping a Pop or a Pops? Say I dropped two. Would it be Pops or Popses or Popes? Maybe it would be better to say,

"I dropped a Pop. es sssssessss."
