Puddle Widening on new position of NPCs Body after death, can anyone help?

I want to have this "puddle" spread outward and i have made it work when the NPC it is in dies, it spreads randomly outward in seperate places, but once the npc has flown away or slid from the attack, the puddle is at least 10 studs away from the body. I have tried to make it spawn on the general position of the Humanoid root part on the NPC, but it wont do it. Maybe one of you smarter people could help out. All help appreciated! EDIT: I need for this code to work still, but execute at the position of the dead NPCs body. Code:

local Char=script.Parent
local Hum=Char:WaitForChild("Humanoid")
local Tor=Char:WaitForChild("Torso")
local M=math.random
local R=math.rad
local rates={0.05,0.075,0.1,0.15}

local smooth=function(P)
local SM=Enum.SurfaceType.SmoothNoOutlines
P.TopSurface=SM
P.BottomSurface=SM
P.RightSurface=SM
P.LeftSurface=SM
P.FrontSurface=SM
P.BackSurface=SM    
end

local function BloodPool(Part,Size)
local Pool=Instance.new("Part",game.Workspace)
Pool.TopSurface=0

Pool.Transparency = 0.5
Pool.CanCollide = false
Instance.new("CylinderMesh",Pool)
Pool.Anchored=true

smooth(Pool)

local c=Part.CFrame*CFrame.new(M(-3.01,3.01),-2.9,M(-3.01,3.01))    
coroutine.resume(coroutine.create(function()
local rate=rates[M(1,#rates)]
wait(2)
game.Debris:AddItem(Pool,15)
for i=1,M(25,70) do
wait()
Pool.CFrame=c
Pool.Size=Pool.Size+Vector3.new(rate,0,rate)
end 
wait(5)
Pool:Destroy()
end))   
end

local function BloodDrops(Size,Area)

Blood.CFrame=Area*CFrame.new(M(-1.00,1.00),M(-1.00,1.00),M(-1.00,1.00))     
return Blood
end


local Heath=Hum.Health

Hum.Changed:connect(function()
if Hum.Health<Heath then
Heath=Hum.Health        
for i=1, math.random(4,10)do
local Size=Vector3.new(M(-0.25,0.25),.05,M(-.25,.25))
local Blood=BloodDrops(Size,Tor.CFrame) 
local Stopper=false
local Size2=Vector3.new(M(-0.25,0.25),.05,M(-.25,.25))
BloodPool(Tor,Size2)
end 
end
end)
