Do you know the plural of a Jewish toy called something like "sevivon"?

I just listened to this song. I googled the lyrics, and the line I am wondering about seems to be

“Sevivon to play with, and latkes to eat.”

There is another version which replaces “sevivon” with “dreidels”. However, in my link, there seem to be four syllables, and “sevivon” only has three. The term sounds like “sevovinon” or something similar.

Could this be the plural?
