I got on the phone with a Cassowary friend of mine in Queensland last night and found out a bit of history on the MIB dudes. Apparently they were brought in as distraction/entertainment from Transformers construction, however, they proved so popular that management decided to keep them on. Apparently, their budget may have come from elsewhere in the resort, however, my Cassowary buddy could not, would not, shall not, doughnut, and clam chowder, elaborate.
Cassowaries can be so darned mystical.
