Just saw the His Dark Materials series and...I'm kinda bummed about the design of the Mulefa? I mean, they're cute, but they're too normal-looking.
The books went out of their way to describe that they had diamond-shaped skeletons with one front leg, two side legs and one hind leg, and had a two-pronged trunk they used as an arm. They're aliens, and the show made them a bit too familiar and not quite alien enough.
So here's my take on them trying to keep the original anatomy and maximize the alien-ness factor. I imagine the front and hind legs have to be really short with very long claw axles to make the bike-wheels work better, so when they don't have any seed pods on they're bipedal and walk on their two side limbs. Their trunk would also have to be less tapir and more elephant to actually work as a prehensile organ.
Also pictured: the Tualapi, a predatory "bird" that is the natural enemy of the Mulefa. Nice that they also have diamond-shaped skeletons as evidence of "rhombotetrapod" ancestry, but it's a bit odd how the wing sails moved to the back and somehow bypassed the head and neck.
