Nurse Spiders are missing sounds when healing

They have unused sounds in the game files. This is what they're supposed to sound like when they heal:

    State{
        name = "heal",
        tags = {"attack", "busy"},

        onenter = function(inst, target)
            inst.Physics:Stop()
            inst.AnimState:PlayAnimation("heal")
	  --inst.SoundEmitter:PlaySound("webber1/creatures/spider_cannonfodder/heal") --This line is missing
        end,

        timeline=
        {
            TimeEvent(30*FRAMES, function(inst)

                -- DANY
                --inst.SoundEmitter:PlaySound("SPIDER SMOKE SOUND") --replace this with "webber1/creatures/spider_cannonfodder/heal_fartcloud"

                inst:DoHeal()
            end ),
        },

        events=
        {
            EventHandler("animover", function(inst) inst.sg:GoToState("idle") end),
        },
    },
