How do I get rid of the octopus?


Hint 1 of 8:
The octopus is probably hungry.

Hint 2 of 8:
It wants to eat something that it might find floating in the water.

Hint 3 of 8:
There are all kinds of crabs around the place.  See if you can bring one to
the octopus.

Hint 4 of 8:
You will need a rib cage from the subway to trap a crab.  The subway can be
found on the very outer circle of Atlantis, as piles of rubble in the
corridors.
