How do I island climate

[This Accelgor is actually doing something none of his companions would ever do: get someone to help (them) out. His metal companions and raised-by-wolves human-like trainer are dying in this weather. Accelgor? Not so much, his membranes keep him cool and hydrated all the time awyeah. You may not like him, but he at least trusts you and Purrloin to do something about this? He wants you to follow him somewhere :I ]
