Kingdom of Knuffel

Your familiar needs to be an epicurean animal, that can distinguish a crazy amount of flavors and tastes. Because only such a familiar can truly appreciate the privilege of "licking the spatula" which is granted to your bonded beastie.
Problem is, I'm not sure what that would be.

Let's make something up, then.

The mythological-level familiar of the Vatch. Born when a batch of magic-infused batter is baked just right.

Your familiar is a brown bear.

Your familiar is an armadillo.

Your familiar is a Red panda.

Sugar-glider!

Because puns.

You have a golden retriever

i think you have some sort of very fluffy moth!

You have a rat

Your familiar is a dolphin.

I think you have a ferret; they are very clever. This one likes to dress up as a pirate and pretend to make people walk the plank.
