I do hope she wasn't practicing with the hobos below the street with the promise of a warm meal... that's what i do, that would be copyright infringement. just kidding.
Get her a horse or something. That should keep her from killing people when she's bored.
this is no place for a horse
Sure it is. Put it in her terrarium.
i am not sure you know how large horses are.
I am sure that I know exactly how large horses are. One horse fits in one terrarium. That's why they are called terrariums. Terrarium stands for "one horse fits in here." It was their preferred containment method in the early Greenhouse and Potted Plant Period.
and here i always thought terra meant land or something
So it does. That is why the scientific name for a horse is "Terra-horsebeast," not to be confused with the "Aqua-horsebeast" or the "Avian-horsebeast." So only a land horse will fit in a terrarium. You'd need an aquarium or an aviary for the others.
