While none of the people who are stuck in guests of the Amazing Digital Circus are happy to be there, most of them still choose to participate in Caine's fun games and jolly scenarios, but not Zooble: Zooble generally refuses to take part in anything unless they're forced to, preferring to just stay at the Circus and sit things out, even when Caine builds adventures specifically designed to appeal to them. The problem? It's nothing to do with the adventures, really; Zooble in unhappy with their body, doesn't like themself, and wishes they could find something that feels right, and that's a more pressing issue than whether the candy kingdom gets saved or whatever.
Zooble's avatar is based on ZoLO toys, the '80s/'90s line of oddly shaped, brightly colored pieces that could be assembled into whatever creations you wanted (though the name comes from a different building toy, Zoobs). In the show, all their limbs 
and other pieces are swappable, and they have an entire box of extra parts, so they've got a minorly different design in every episode (with mainly the head and torso staying the same). So far these minis have all been based on the first episode, so that's the particular Zooble we get here: one lightning bolt horn, one blac-and-white striped Y horn, a single pink wing, a circular thing on the chest, a rubber hose right arm, a springly left arm with a lobster claw instead of a hand, a left leg that ends in a shoe, and a right leg that ends in a curlicue spiral. That may work in animation, but it would make for a very fragile, unstable minifig, so Zooble is sculpted sitting on the ground with their arms crossed, looking steadfast and stubborn - not the most exciting thing, but at least it won't fall over or break.
Glyos joints would be perfect for this system, just saying.
