I do not know what is more clever - the music of Mikis Theodorakis, the story of a obsessed octopus for cleaning, the ice cream stains ignored by janitor, preocuped by the ink signs of warning or the wise crafted two minutes animation.
The story is more than simple and amusing and you feel it as a wise parable - ironic in essence- about ordinary realities.
You discover a great univers in its simple traits , old fun from childhood and a so ...pink octopus as a sort of hiper correct citizen.
So, all is more than familiar and used in admirable manner for a precise message, fair moral story and the janitor tasks.
