Ok, to build on jafe's answer:
Part 1 is
Shoe (this one I did not get)
Part 2 is
And I think part 3 is
Because of the
Bovine reference, it being necessary for life since we all need milk as babies
and also the mention of
blocks which I believe are blocks of ice which people would put their milk and other perishables on.
However the final solution eludes me. I believe it to be a
three part word or phrase made up of the following wordparts
to be determined:
____ shoe or shoe____
____rep or rep_____
____milk or milk______
But what could it be?
Is it Gazeulsionmaid? j/k
Is the answer to the bovine line in part 3
invisible as in invisi-bull?
So now I think part 3 is... (Drumroll)
So the word could contain these letters
per and hose
Ugh, I give up for now.. am I on to anything?
