Help with monster statting

[Shnigda]

Hi guys, I've been rereading the Zamonian books by Walter Moers recently (Rumo, Captain Bluebear etc...) and thought it might be fun to include a couple of the monsters or characters from the books as monsters or NPCs.

However, I'm not at all experienced with monster creation, so if anyone with knowledge of the books (or not) could help that would be much appreciated!

Creatures I've thought of so far that might be good:
- Spiderwitch
- The muggs
- Echo the Crat
- Rumo
- Bluebear (maybe including influences from his lives? Eg pirate class from his time with the minipirates?
- Professor Nightingale
- Knio
- Deus X Machina (Mac the Roving Reptilian Rescuer)

Of course feel free to stat any others you can think of!

Thanks!
