The relation of Hades to the Kraken is obvious! How can you literal-minded folk have such a narrow purview of human creativity!
Everyone knows that the Kraken is the house monster of Hades, of course!
Provided that everyone gets their knowledge of the Perseus myth from that modern Titanomachia cum Perseiad, Clash of the Titans (2010 film).
Added bonus: there’s Djinn in there, too.
