Although Chip says that Cassandra was wrong about her predictions when he survives the adventure, Cassandra was right on all of them. Like Gadget said, she did not mean the elephant's trunk, but the pirates trunk. "then, all is darkness" must have been seen by her from Chip's position who was hiding in a probably dark hole in the floorboard. The slashing throat motion and noise was mimicked from Abbadabba, who did the same, probably having noticed the trunk falling towards Chip or believing the Rangers inside would die from that fall. Finally, when Dale and Chip see Cassandra again to confirm what she saw, Dale exclaims Chip is his best friend. Cassandra replies that she saw that to. This means she saw what happened after Chip was rescued from his hole when Dale pounced on him calling Chip his best friend. Why Cassandra did not realize this meant Chip was still alive after all or why she withheld that part from the Rangers is unknown. Perhaps she did not even consider that everyone thought it would end fatally.
