Inspired by the cool fact that temperature determines the sex of most turtles. warmer temperatures produce female hatchlings, while cooler temperatures produce males.
If Chel (pure water) is male, then it evolves into Glascute and then Glachelon (both water/ice type).
If it is female, then it evolves into Blazcute and Blazhelon (both water/fire type).
