Etsy user tinyminds makes cheap, wonderful solar-powered robots for between $60-$80 each, but the one pictured here is christened after Lord Cthulhu, H.P. Lovecraft's sickly spawn of the stars. The Cthulhu bot sleeps until he soaks up enough light... at which point, he begins to madly thrash around his many sucking, tentacled limbs. "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn..." as the ancient prophecies write. Roughly translated? In his house at R'lyeh, dead Cthulhu waits recharging.
