Pulling from a question in a different thread - what EXACTLY does it mean when you state a snake is going into "blue" phase and then "opaque" phase. I noticed Flicker's eyes go blue - and I know that means he's sending fluids under his skin to loosen it - and he does look darker and more "brown" during those times... but his eyes don't stay blue - the fact that he's darker, does tht mean he's still in "blue phase"? And what is opaque phase?
