There's a Fluffal Fusionist but its just a Fluffal with a Scale effect to fuse.
There's also Frightfur Bone Diver and Frightfur Claw Pirate, but those are all Main Deck stuff too
I would've thought Nightmary would've been a Pendulum due to being the ultimate boss of the Pendulum-focused Frightfur manga deck but nah.
