Hermit Crab Potholder or Fish Bowl Mat

I'd love to see this used as a mat for a fish bowl!  I created it with lime green yarn and a white yarn that had bright turquoise flecks.  I think it looks just like a green turbo shell--a favorite selection with my hermit crabs.  The eyelashes are the perfect finishing touch.  I'm not sure if I'll ever be able to re-create it, so it may be a one of a kind.  It is nice and dense and 100% cotton.
