this works when a players proximity spawns a poison spider or pig from one of its 4 spawners, then steps onto a presser plate that activates a dispenser full of slime eggs. then the chain reaction takes place and the area is flooded with slimes. works best in an enclosed area. and sometimes takes a bit to work.
it is the small black box in the image shown from above
this is an ok trap. it could be better
