For her part, Nel has not even considered the risk of a cave-in within the tunnels. If there was a danger, she trusts that the dormice would give them some sort of warning. Still, she does not know what might be needed, “It couldn’t hurt. I think I have some candy in my bag...”

Then her attention turns down to Russell’s legs. Specifically where his knees happen to be in height to her. From that, at least she can guess the bare minimum of space he may need to avoid crawling if she adds his head and neck to it. Crouching to enter seems like a fair compromise. She holds a hand about where that looks to be and asks, “So maybe if I find a hole this tall?”

Clearly her job will be to search for a hole while he gets supplies.
