local Brick = game.Workspace:WaitForChild('Brick')

local Clicked = false

local function UpdateMovement(Pet, Base, Position)
		local Direction = CFrame.new(Pet.Position, Base.Position).lookVector
		for i = 1, 10, 2 do
			Pet.CFrame = Pet.CFrame +  (Direction * Position)
			wait(0.05)
			if Clicked == true then
				break
			else
				return
			end
		end
end

local Activated = false

Tool.Equipped:connect(function(Mouse)
	if Activated == false then
		Mouse.Button1Down:connect(function()
