:Clone() causes massive fps drop?? [SOLVED]

Uh so yeah, look at this. As you can see I get a huge fps drop after the fireball exploded, how and why does that happen?

local Tweenservice = game:GetService("TweenService")

end)

Oh right , fixed it by myself. I change those effects parent from workspace to player character.
