She's so tiny too! Have fun watching her grow. When she gets bigger she'll be a real bruiser. They're one of the harder hitters and need to exercise their smashers to avoid atrophy. Make sure she's got some snails and hermits to wail on wherever you keep her.
Mine is super shy as well. If you want to see more of yours, you might want to try setting up a video camera when you leave the house. I did this and was surprised to see how active mine is when I'm away. I wouldn't be surprised if she recognized the sound of the garage door as a sign of my leaving because on active days, she takes a few trips out and about within the first 20 minutes. When I'm home, I pretty much just get stared down from the burrow.
