Kingdom of Knuffel

Your familiar has to be one of those talking animal familiars that accompany Magical Girls on their adventures.

Not sure if those are ever a real species or not...

I think yours is probably vaguely cat-shaped, but maybe has a tufted tail and tufted ends to its long ears, and super long, elegant whiskers!

You have a big fluffy owl as your familiar.

You have one of those really classy sea-horses that look like seaweed or coral, with all the trailing fins and fantastically shaped eyeridges....

Why have a white dragon when you can *slaps the after mentioned dragon* this rainbow dragon as your familiar. Comes jammed pack with every colour of the rainbow.

Hmm hmm hmmm....

Okay for some reason right now I'm really feeling a manatee as your familiar.

Super mellow, calm, patient. Listens to everything you say without judgement.

You have a chameleon so it can change to any colour you want.

You have a very majestic black horse

Your familiar's a beautiful raven.

You have a vibrantly colored bird as a pet. Like a quetzal?

You should have an albino bat!
I think it would fit in with your aesthetic very well indeed :)
