How am I supposed to finish W-D40 off?

Hint 1 of 6:

Make sure that she can no longer cloak.  You need to have taken care of her
as described earlier in this section, before you can finish off these hints.

Hint 2 of 6:

Have you tried eating the fruit that you found (see the last question for
hints if you don't already have it)?

Hint 3 of 6:

Then you know that it could really plug someone up.

Hint 4 of 6:

I bet it might even work on an android.

Hint 5 of 6:

Try to find a suitable place where you can "feed" her from.

Hint 6 of 6:

I'd say that the middle of that hollow log is a good place.
