I have to admire the octopus.  Natural escape artists, these critters
can pretty much navigate any ground (though I suspect putting one in a
desert would end out poorly).  This tiny octopus is determined to get
back to the water--and does so with what I would term "ugly
gracefulness" in this video uploaded by ParryGripp on December 25, 2012.

Looks like one of H.P. Lovecraft's Cthulhu to me--only micro-sized.
