Custom made and painted by Adventure Bricks, these slimes are 6 studs long and 4 studs wide at the front. You can choose between the low-lying slime vs the tentacled slime based on how sentient and mobile you like your slimes to be.
Our slimes are built on lego baseplates so they can be stuck to walls (or ceilings) if you have studs on them.
Wait - so cities in Pathfinder have sewers? Hmm.... that's pretty advanced. :?
