I love cute, but I'm not so sure Chitter and Pool would produce "cute". Right now we know them as children, so yes they're cute. Yet Chitter already has a strong personality and Pool has, very maturely for his age, come to term with his awesome gift. A child with such a strong will and a gift of that scope could end up as powerful as Rayek. Let's watch out and make sure he/she is raised well.
Chitter and Sust are more likely to produce a "cute" mixture with a result halfway between Skot and Pike.
