I recently came accros a stoney in a room that /shouldn't/ have stonies, so I implemented a small script to replace stonies with fatties IF the game randomly decides that an enemy should get replaced with stonies.
So if the my mod finds a stoney:
- In the basement/cellar => normal fatty
- In the burning basement => burning fatty
- In the Chest => blue conjoined fatty
- Everything inbetween becomes a pale fatty, with a 25% chance to become a fat sack
Haven't come accros any portals yet, so won't make a script for it /yet/.
