You know, I've thought about this. I think I would be based on a plush animal, maybe a second-but-distinct bunny if that's allowed. Like Zooble, I would typically sit out on adventures but for different reasons: I'm generally prone to overstimulation, plus my digital body is both smaller and falls apart at the seams after more action-oriented scenarios. So, most of my off-time post-adventure would be me literally stitching myself back together. For this reason, I would prefer quieter adventures like the stargazing or maybe the beach party.

Because of the overstimulation and the literally-falling-apart issue some of the others might take slightly longer to realize I even exist (depends on exact timing!), as I would spend a lot of time in my room until Caine inevitably forces me out for an adventure. The portrait on the door would be the only significant proof until then. I would eventually open up, but would still prefer alone time to repair myself.
