Muddy swamp introduced here. Could someone try to turn this into an article at some point?
Also, based on
189 #define likes_swamp(ptr) ((ptr)->mlet == S_PUDDING || \ 190 (ptr)->mlet == S_FUNGUS || \ 191 (ptr) == &mons[PM_OCHRE_JELLY]) 192
644 if (is_swamp(mtmp->mx, mtmp->my) && rn2(3) && 645 !is_flyer(mtmp->data) && !is_floater(mtmp->data) && 646 !is_clinger(mtmp->data) && !is_swimmer(mtmp->data) && 647 !amphibious(mtmp->data) && !likes_swamp(mtmp->data)) 648 return(0);
it looks like certain monsters are better at moving in swamps than others.
That should probably go into this article, but the ones that specifically like swamps (Puddings, Fungi, and Ochre Jellies) might get a sentence added to their pages?
Ok, I tried to add some more info to this article, but I know I'm leaving out a lot.
