Reader bitties come in all shapes and sizes.

Many are humanoid or bipedal, while others have animalistic or fantastical features.

Reader bitties are created by an excess of emotional magic manifesting into a physical form. Because of the multiple AUs breaking through the barrier in the same location, there is more loose magic than normal in Ebott City.

This means there are Reader bitties appearing almost every day all over the city. Royal Guards are often called to take 'Wild' Reader bitties to the shelter when they are first found.
