Squid and octopods jet across a map of the voyage of the HMS Challenger. In calming shades of oceanic blue, this notebook makes the perfect place to draft your novel or keep a travel journal of your epic adventures, complete with illustrations of the strange new things you've discovered. Cephalopods can change texture, shape, and color faster than a chameleon, have three hearts that pump blue blood, and can “disappear” in a cloud of ink. Fill this notebook with notes about the magical species, or gift it to your squid-loving lab partner.
