[You know that she can't help you in this fight, Dean. And to make sure of that, when she attempts to step forward, one of the smaller Deku Babas from the side lunges out and snaps at her. She shrieks and stays put right where she is.]
If you hit it with a Deku stick, you will do more damage!
[Clue number two. The giant Deku Baba, in the meantime, watches Dean roll out of the way and then laughs a deep, taunting laugh. Yes, it can do that, because this is a dream. It then shakes his head and lunges again, jaws wide open to try to grab him.]
