Back in classic at the time it was reserved for level 51+ mobs. Most animals didn't summon. I remember very very clearly from the countless hours spent in Sebilis back in those days that there was NO frogloks that would be able to summon except Krups Ilis and reets. Krup's weren't always able to summon (they could range from 49-52), and ilis/reet always summoned. There was only one ilis that did NOT summon and that was the ilis acolyte which is level 50.

Hope this helps.
