Probably because the word is "hoops", without the "e"; the plural of "hoop".

Right, but if you notice, the e and the s are adjoining keys on most common keyboards. Apologies if my wording was confusing, but I didn’t call out the es as the OP misspelling the pluralization, but rather specifically as a typo.

My mention of misspelling was there only to prevent another person from pointing it out, but alas, I still failed it seems.
