Suggest a monster to appear in an upcoming Fertile in My Ex-Boyfriend's Dungeon (Patreon)

So I'm going to let you guys pick one monster in an upcoming Fertile in My Ex-Boyfriend's Dungeon. This is not #4 or #5, which are already fully planned out and locked in, but for #6. The monsters in #4, #5, and what I have planned for #6 are...

------------------------------------- SPOILERS--------------------------------------------------------

Undead pirates, fish men, a kraken-like tentacle beast, a cow monster girl, a horde of perverted maniacs, a mad alchemist, a gnome, and a troll. 

So for the one with a gnome and a troll I would like one more monster of the sort that might be found in a fairytale setting. I can think of some possibilities, but I would like to turn to you guys for suggestions. A couple notes:

- No demons. There will be lots of demons in upcoming books.

- No undead. 

- Probably not a monster girl unless it is really good. I want to limit how many of these I use.

- If it is a beastlike monster it must be intelligent or very fantastical to avoid limits on content.

What do you think would be fun for Beatrix and her companion to encounter?
