i Just checked it out in one of the other forums, ( looks like the one for UO HALL is the most productive) therer is a list kicked as to the locations of the spawns check out the "anyone know where the slimes are" thread on uo hall.
as for today and yesterday our little fellas are in the Ilsh dungeon know by two names, the sorcerers dungeon or terort skitas. Heres how you get there, come out of the valor moongate and head southwest to cross the river ( like you were going to the champ spawn), then follow the river to the south untill you get to the foot of the mountain thats it, now if you die in the dungeon because there are some nasty paras in thereyou can exit the dungeon and roll down stream to a healers hut. the slime are located on the second floor of this dungeon in the round room located in the southeast section of the second floor. There are new colors. enjoy.
