It's training, pure and simple.This little guy used to be afraid of water.I couldn't forgive him for running away from his weakness like that.So we trained.I made him swim laps over and over, pushing him to his limit and beyond.And now his hide is stronger than any other Sandslash in the world.He's overcome his fear of water...And his weakness of water attacks with it!That's insane!He split the field right in half!Wow...*ka-chak*Confused?Take a break and rest up, Lapras.Water attacks won't work? I didn't see that coming...Want to know why it's immune to water?It's not a special ability or anything like that.
