Pippa, the pixie without wings, is kind, curious, and determined. Design wise, it was important to go for the poor girl aesthetic when drawing her; particularly something akin to what one could have seen from the 1930s. I was watching a LOT of Marx Bros. movies at the time I came up with her and it probably kind of shows. Pippa's hair curls are meant to be reminiscent of the antennae some fairies are shown to have, and the hair even slightly hints at wings.
