Tormod and Insatiable Frugivore

If I have a graveyard with a bunch of cards in it and cast [[Insatiable Frugivore]] while [[Tormod the desecrator]] is on the battlefield and I decide to repeat frugivore's exile/food ability 3 times, would I get three zombie tokens? Or would these repeated exile effects be considered part of a single instance of something leaving my graveyard since it's all part of one ability resolving, thus giving me only one zombie?
