Is enzyme 42 dropped by the sea emperor leviathan juveniles?

Am I right, that the sea emperor leviathan juveniles drop the enzyme 42 occasionally? I chased one of the juveniles for 4 in-game days and it didn't drop a single item. How often do they drop the enzyme? Does it fall down to the ground immediately or is it floating in the water?


After they hatched, you find a ball of enzyme 42 right inside the sea emperor aquarium inside the primary containment facility. I also found some balls right outside the portal near the alien tower, where the sea emperor babies left the containment facility.

I'm not sure if they drop more enzyme 42 after/besides that...


  1. They usually drop them inside the Primary Containment Facility aquarium or right outside the Quarantine Reinforcement Platform

  2. They float
