Some days, it’s a flying, invisible snake with horns. Other days, it’s a pixie that can carry people up a mountainside.
Not today though.
Today it’s a ferret that drops the F bomb.

Not much of a fight, not much of an encounter at all really. Depending on your outlook, this is either the best or worst kind of pet. On the one hand, it’s a big, beefy ferret that you can talk to. On the other hand, it only wants to use it’s understanding of language to cuss. To some, that might be the very best kind of animal companion.
