how to re-size a r6 player im getting a glitch when attempting?

wait()
local mouse = game.Players.LocalPlayer:GetMouse()
local player = game.Players.LocalPlayer
character = player.Character
db = false
shooting = false
dmgdebounce = false
damage = 60
myname = player.Name
if game.Players.LocalPlayer.data.dmg then
	damage = damage + game.Players.LocalPlayer.data.dmg.value / 10
end

mouse.KeyDown:connect(function(key)
	key = key:lower()
	if key == "g" and db == false and shooting == false then
		shooting = true
		if db == false then
			db = true
		character:FindFirstChild("Left Arm").Size = Vector3.new(1.2, 2.4, 1.2)
		local joint = Instance.new("Motor6D")
		joint.Parent = character.Torso
		joint.Name = "Left Shoulder"
		joint.Part0 = character.Torso
		joint.Part1 = character["Left Arm"]
		
		character:FindFirstChild("Right Arm").Size = Vector3.new(1.2, 2.4, 1.2)
		local joint1 = Instance.new("Motor6D")
		joint1.Parent = character.Torso
		joint1.Name = "Right Shoulder"
		joint1.Part0 = character.Torso
		joint1.Part1 = character["Right Arm"]
		
		character:FindFirstChild("Left Leg").Size = Vector3.new(1.2, 2.4, 1.2)
		local joint2 = Instance.new("Motor6D")
		joint2.Parent = character.Torso
		joint2.Name = "Left Hip"
		joint2.Part0 = character.Torso
		joint2.Part1 = character["Left Leg"]
		
		character:FindFirstChild("Right Leg").Size = Vector3.new(1.2, 2.4, 1.2)
		local joint3 = Instance.new("Motor6D")
		joint3.Parent = character.Torso
		joint3.Name = "Right Hip"
		joint3.Part0 = character.Torso
		joint3.Part1 = character["Right Leg"]
		
		character:FindFirstChild("Head").Size = Vector3.new(1.2, 2.4, 1.2)
		local joint4 = Instance.new("Motor6D")
		joint4.Parent = character.Torso
		joint4.Name = "Neck"
		joint4.Part0 = character.Torso
		joint4.Part1 = character["Head"]
		
		
		
		
		
	local originaldamage = player.data.dmg.Value
	player.data.dmg.Value = player.data.dmg.Value * 5
	wait(60)
	damage = originaldamage
	
	
	
			wait(15)	
			db = false
	shooting = false
		end
	end
	

end)

it makes your entire body combine into one small head thing its weird...
