This may be why it is best for Cthulhu to never appear on screen. It is going to be very hard to have him not appear as something from a kids show. Now, the ironic thing is this. The Alert was supposed to meet the dread one around mid March 1925. Know what else occurred during that time? The Tri-State Tornado.
Some storms even produces something very like tentacles
I might try a link there, but end it with something along the lines of "What The moon brings" to see the Dread one only at the last.
