Okay but imagine being the team of Eridian scientists tasked with keeping Erid's Only Human alive for as long as possible while the whole planet's environment is literally trying to kill him. And then Rocky shows up and is like:
“Grace says he would like half of dome to be water.”
“Oh, is necessary for humans to have large amounts of water question?”
Small Eridian equivalent of a sigh. “No. Not needed for life. In fact Grace will die if he falls in water and does not get out.”
“Tell him we give him water in containers that won't kill him. Lots lots lots of water on Erid for Grace to drink.”
“No. Grace say he want water on ground. Also want it with excess sodium chloride compound so it will be unhealthy for drink.”
