Riptide Octopus Swarm

CREATURE 0

Riptide octopuses have adapted to these isolated hunting grounds with their strength, pulling themselves hundreds of feet across dry land to check their territory's pools for prey. Under most circumstances, such mollusks are solitary. However, massive scavenging opportunities like a beached whale or a wounded mammal can draw hundreds of these creatures to one place.

Eater of Toes

The riptide octopus didn't get its name from living in tidal zones but from being more stubborn than a riptide pulling someone out to sea. Beachcombers know not to dip their toes into tidal pools lest a riptide octopus mistake them for prey, and many bear scars that remind them of the dangers of ignoring such advice. Dislodging a hungry riptide octopus sometimes takes extreme measures in the form of a crowbar; fortunately, the octopus's skin is sensitive to fermented fluids like vinegar and wine, and dousing the creature with such concoctions usually encourages it to detach and flee.
