WTF is on googles home page

Am I missing something here because I have clue what their halloween puzzle is about.

Are we supposed to mix some sort of brew with those items in some unknown order?

what about the coffins?
Is there one we are supposed to pick?

If this is just some stupid ass nonsense that never ends, ,......

Perhaps clicking the search icon Google provided adjacent to the Doodle that provides all the info you need about the Doodle will yield the answers you're looking for rather than having to post on a forum about how you're so confused.
