How do I make my particle system detect/mark a floor collision?

Hey, Sorry this may be a dumb question. I'm having trouble making a particle system component detect and mark the location of a collision with a plane game object.

What I want is spherical gameobjects to come out of a dead enemy object and mark the floor (Similar to blood splatter) with blue puddles.

The only way I can think of achieving this is by having the particle system produce separate gameobjects with scripts attached however I can't do so. Any help on this would be greatly appreciated :D Thanks!! - Taylor
