@ Ribbon, Water Veil protects you from the Sauna Cave burns just like any other kind of burn.
@ Ice, There’s nothing within the current realm of PMU’s features that can provide that all-terrain trait right now (outside of getting messy and coding it in for the specific Pokemon that mess with the typical convention). This is an ability update, although I can see something like an IQ coming out of what you’re getting at in the future.
@ Ino & Prinplup, there will be an update in the future that will reveal genders. Once you’re all shocked and horrified of the random number generator’s curse in picking your gender, you can all go to a mod and ask him or her for the grace period of gender changes that will be available during that week or so.
