A snow-white Pomeranian transformed into an adorable Halloween spirit guide, their cloud-like fur glowing with an ethereal moonlit aura. Their naturally fluffy coat resembles a miniature cumulus cloud tinged with subtle purple and blue ghostly highlights. Tiny, decorative spider webs made of silver threads sparkle between their fur spikes, catching dewdrops that glow like tiny stars. Their alert black eyes now have a playful supernatural gleam, surrounded by a subtle mask pattern created by iridescent moonlight. A small, ethereal witch's hat floats slightly above their head, seemingly suspended by magic, decorated with star-like fireflies and wisping smoke tendrils.
