[Zelda stops and gasps as soon as she sees the giant plant, her hands flying up to cover her mouth. The monster notices them at the same time, and it lunges forward, snapping at them even though it cannot reach them just yet.]
That is a Deku Baba!
[That's all the help you're gonna get from her for now. She will not move from her position until you get rid of this monster for her. Feel free to look around for some items if you need them. There are bomb flowers spaced out around the perimeter of the clearing, and one smaller Deku Baba on either side of the steps that can be destroyed with a single kick. These will produce Deku sticks that can then be used to whack at the bigger one to deal it some damage.
Please note, Dean, that any weapons you may have brought with you into the dream will not work against the mini-boss. Only Zelda items will be able to defeat it! Have fun~]
