The pink comb tantalizes me! How can I get one?
Solution 1:
This link has a list of every weapon attainable in the game and how to unlock them all. It does not have the comb as a usable weapon.
I have every animal orb in my game and I know you don't get a comb from those.
However you can unlock one weapon in Medusa's lair. The Buster Sword.
