Wren has four moods: Adorkably happy, pouty birdy, mopey baby, and horrible goose

There's no in-between whatsoever, it's one of these moods and it's damn near impossible to tell which mood she is at the moment for it can change in seconds. One moment she's mopey and the next adorkably happy because she found some unidentifiable Shiny Thing and wants to admire whatever it is like the little crow she is and then horrible goose when she finds a tree in walking distance and pouty when she can't climb it because it's too smooth and slippery to climb right.
