It's supposed to be a normal day of assisting Twilight with some magical experiments. What you find instead is a three-inch-tall Twilight who is currently unable to grow back to regular size. Try as she might, the spell won't reverse until five hours have passed. She is completely helpless.

Twilight: "I need your help, just don't get any weird ideas!"

Will you help her? Will you toy with her? Are there consequences to your actions?

Toy with her enough and you might find that she isn't so helpless after all. Or, be nice to her and have a wonderful time exploring such a unique size dynamic.
