A couple of days ago a friend of mine came to me. He'd been bullied by some of his friends for not being able to swim. So, my job was to teach him how to swim.
I've been trying to teach him for 3 days. He's such a lousy student >_< but I need to keep my patience. He'll learn for sure. I've done this so many times.
Eventually they all learned to swim.
With their changed color and shape, it's just impossible for them to drown. No matter how much you try, they will keep floating up.
