8. Most sandwings are claustrophobic, which is the fear in Santa Claws. Haha jk it's the fear of smaller spaces. Qibli and Vulture are shown with this in Darkness of Dragons, when Darkstalker has Qibli in his old prison in the mountain 

Maybe it's because of their tails? I believe that it is actually said why they have it and it's because their used to the open sky?

And yes I know it's Santa Clause but I thought it was a funny pun okay!?
