Using tweens to rotate changes part's position to 0,0,0

[HearTheThing (Increstagator)]

When tweening this with angles, the eye rotates but for some reason it sets its position to 0, 0, 0. Does anyone know why?

Start Position:

End Position:

Script:

local info = TweenInfo.new(0.25)
local TweenService = game:GetService("TweenService")

while true do
	local x = math.random(0, 80)
	local y = math.random(0, 80)
	local z = math.random(0, 80)
	local goal = {}
	goal.CFrame = CFrame.Angles(math.rad(x),math.rad(y),math.rad(z))
	TweenService:Create(script.Parent.PrimaryPart, info, goal):Play()
	wait(math.random(1, 4.5))
end

try:

local info = TweenInfo.new(0.25)
local TweenService = game:GetService("TweenService")

while true do
	local x = math.random(0, 80)
	local y = math.random(0, 80)
	local z = math.random(0, 80)
	local goal = {}
	goal.CFrame = CFrame.new(script.Parent.PrimaryPart.Position) * CFrame.Angles(math.rad(x),math.rad(y),math.rad(z))
	TweenService:Create(script.Parent.PrimaryPart, info, goal):Play()
	wait(math.random(1, 4.5))
end

you’re giving the CFrame no position so it’ll default to 0,0,0
