I am so sorry to decieve you ;__;
Swift Swim indeed looks like it involves Water in some special way, but it doesn't. XD
The truth is tat, when I started this hack, I called it Aqua Blue (like Fire Red/Leaf Green) because I was too lazy to use my stupid brain. xD
Later on, since there is only 1 starter in this hack, and since it has the ability Swift Swim, I changed the name to that, I like that ability and the name as some sort of nice sounding.
