Why didn Sleipnir (Odins horse) have eight legs like he does in Norse myth?
Greg’s answer: Sigh. I wanted Slep to have eight legs. But Frank Paur and Bob Kline convinced me that it would just be too hard for our overseas animators to draw. We agreed that a well-animated four-legged horse was preferable to a poorly animated but accurate eight-legged horse. In my head, Slep still has eight legs, but as a changeling himself, he can choose to appear with four legs if he wants.
