In my opinion October is a month of tentacles (because “Octo,” and also because spooky season)

And October also has the opal for a birthstone

Therefore the best gift to give in October is an opalized ammonite fossil

Yay shiny

(ammonites were cephalopods and probably had 10 arms not 8 but that’s ok)

(opinion totally not influenced by my Ram fixation and how ammonites are ram’s horns)
