I'm quite surprised that there isn't a Pony LoRA for this character yet. So here you go, Mrs. Brisby from the Secret of NIMH (1982).

This LoRA can generate Mrs. Brisby in two body types based on e621 tagging:

• semi-anthro: Mrs. Brisby's traditional body anatomy

• anthro: for a more humanoid anatomy

You can also generate her wearing her signature red cape and wearing the red pendant necklace. Use the sample images for reference.

To avoid random monochrome/greyscale generations, put these tags in your negative prompt.
