The Cat of Palug

And the witch goes “OK, Kay, you killed me. But will you survive fighting the deadly Cat of Palug.”
And Kay stares at her and says “A cat? Seriously?”
And the witch pukes blood and goes “A cat that has eaten 180 knights.”
And Kay looks at her and repeats “A CAT. Boy, we got more killing to do.”
