Being skinny is good, and she shows that.
Well, Barbie is a good role model to kids because she's not dirty :p
She's a good role model because she's a good girl, and she's very nice and sweet.
If your hamster is young, they tend to be hyper. As they get older, they will start to calm down a little. But if it's still happening, put him/her in a ball, get them a wheel in their cage, just try to find out ways to make her tired.
Some hamsters don't like getting picked up, accept it. Maybe it's not tame yet?
Don't show fear, they know if your scared and they will try to bite you.
Is the cage too small? Whenever my hamster tried to escape, it was mainly because she was bored and had nothing to do. So make sure you provide your hamster with a lot of things to do so they won't get bored.
Well, all hamsters bite. The friendliest hamsters would be the Syrian Hamsters. Hope I helped :)
