A grandmother named Lenore decorated her tree with 99 octopuses, one for each of her grandchildren.
She made each of them herself from a pattern called Octophrost, Santa of the Sea, available for purchase from Futuregirl. (Tree Octopus ornaments! Why didn't I think of that?)
Besides being festive, it's educational for the kids, allowing them to see the population density of Pacific Northwest Tree Octopuses prior to their becoming endangered. Someday all trees in Cascadia will look like this again.
