It's interesting that you guys with veileds would say this because I noticed
the same with Smeagol.
When I bring him inside from the sun, he acts very strange, like he is affraid and doent know where he is.
He turns a dark color too. I have to let him calm down for 1/2 hour or so
before I can move him back home.
Now that I hear other stories, I see this is not unusual.
