I made a multimaterial version of IOIIOOO's ghosts. It's untested since I don't have a multi-material printer yet (waiting for the prusa MMU 2.0). The picture is from painted ghosts.
I wasn't able to use meshmixer to modify the original stl files so I had to redo the models in fusion 360.
Could be used for my Pac-Man Maze: https://www.thingiverse.com/thing:2805680.
Please post your make if you can. I'll remove "Work in progress" flag when someone can confirm that it can be printed.
Note: The blue-body STL has errors but slic3r seem to be able to repair it. If I try to repair with meshmixer or in 3D builder, I have trouble when importing the multiparts-STLs in slic3r.
