Increase your anxiety with these lot. They'll be sure to make your experience with them as horrible as it gets.
Just don't put too many down, as it might crash your game. Probably.
Some big NPCs like the Strider are best paired with the Extended AI Navigation addon.

ATTENTION!!!
IF the dupes are not working, reinstall the bonemerge mod!! Sometimes it won't work whenever you download other dupes with this mod, so please don't cry about it in the comments.
