Woohoo, another late night writing a story in one go! In case you people are having trouble imagining how Hailey walks, do a handstand, or get in push-up position, and start walking with your hands. Also Lily's tail is about the same length as Hailey's, and if you need a reference, watch the music video Avenged Sevenfold - Bat Country, if you want to skip right to the scene(you'll be missing out), it's between 1:32 and 2:02.

Edit: Why didn't any one tell me about how many times I dun goofed at typing, I just went through some of my stories fixing the grammar. What is wrong with you guys?!
