I once let my otter Nutmeg on roam so she could harvest some pearls for me. I followed her in the water so I could target coelacanths and fight off any incoming threats. I ended up being savagely attacked by piranhas and saber tooth salmon. I was screaming and fighting them off with a sword while Nutmeg calmly swam around looking for pearls. Crazy day in the Redwoods river.
