I love how every Unown has its own physicality and way of moving. They could easily just do what they did in Emerald and just have them all float around in the exact same way, but they avoid that in most instances. My favorite is X in the 3D games. It looks like it has little arms and legs.
EDIT:
God damn it, Bulbapedia. Why do your images always break? I usually try to avoid linking to your images directly
(by downloading and attaching them instead) to avoid this very issue, but for some fucking reason all your animated images are some png witchcraft that won't be animated if you download it.
