Lusca's thousands of lamprey-tentacle young, brooded in her mouth and turned cannibal by Carl's bloodlust potion.
The Juvenile Octo-Sharks are Lusca's level-30 minions — ten-foot lamprey-like young whose back halves split into tentacles, each ringed with a bicycle-wheel mouth of teeth. Brooded in the thousands inside their mother's mouth (2,000-3,000 per birthing, of which only one or two normally survive), they fight one another for every scrap she catches. When Carl releases a Potion of Bloodlust into the water inside the mouth, the berserking spreads through the pack and they tear each other apart en masse — 'thousands of X's' — clearing the way for the party.
Survivors flee up feeding-slits in the roof of Lusca's mouth; a pain-amplifier variant kills Vadim in his escape pod.
Ten-foot lamprey-like eels with a round, teeth-ringed mouth the size of a bicycle wheel and a back half split into writhing tentacles.
Lusca's cannibalistic brood, weaponized against itself by the bloodlust potion.
