How long ago were the burns? The reason why I ask is that burns can cause infections and with him having the burn on the casque and the eye having issues. I am wondering how recent the burn was?
Little man is a little overweight you can tell by his casque not being slim but pudgy. Plastic plants are not recommended since they will try to eat them same with the moss. Both of those would be an impaction risk. The jungle vines your using (black ones) are known to cause issues because the coating comes off. When they shed and rub their faces on stuff they can get pieces of the coating stuck down in the eye turret.
