Do NOT bring them into the water.
Do NOT bring them into the water. I found out the hard way. I was exploring with my pack of ravagers (a pack of five) and we fell into the water. Two of the five died to Piranhas. To add to the sadness the other two died to a dire bear and then I died on the alpha (RageElixir) to hallucinogenic mushrooms coz of the suffocation damage. They all will be missed
