I hope that’s the correct movie reference, it was eons ago when I saw that particular movie.
It’s a melding of two shows, “Gremlins” for not feeding them after midnight, and “The Trouble With Tribbles” of the Star Trek original series.
The number comes from one tribble having ten offspring every twelve hours for three days. That’s six generations, or eleven to the sixth power, 1,771,561.
One million, seven hundred seventy-one thousand, five hundred and sixty-one, that’s the trouble with tribbles.
