It is probable that if Fred went to the hallway, or John moved to the office, then Julius is a frog. It is certain that if either Daniel grabbed the milk, or John moved to the office, then Greg is green. Chances are slight that if John moved to the office, and Fred went to the hallway, then Brian is green.
