How do I tween the full character with all the parts? [SOLVED!]

Can anyone tell me how I can tween the full character with the legs and arms IN R15

I tried to tween the HumanoidRootPart but it doesn't take the whole character this is my code: this is a localscript inside startercharacterScripts

local UserInputService = game:GetService("UserInputService")
local myPosition = Vector3.new(0,0,0)
local player = game.Players.LocalPlayer
local character = player.Character
local humanoidRootPart = character:WaitForChild('HumanoidRootPart')
local tweenService = game:GetService("TweenService")

function InputBegin(input,gameProcessedEvent)
    if input.UserInputType == Enum.UserInputType.KeyBoard then
        if input.KeyCode == Enum.KeyCode.L and not gameProcessedEvent then
            tweenService:Create(humanoidRootPart,TweenInfo.new(.5,Enum.EasingStyle.Linear,Enum.EasingDirection.Out),{Position = myPosition})Play()
        end
    end
end

UserInputService.InputBegan:Connect(InputBegin)
