Zombie not moving back?

I wanted the zombie to move in a pattern :c

local zombie = game.Workspace.Zombie
local zombie = zombie.Zombie
while wait() do
zombie:MoveTo(workspace.Spawn.Position)
print("Moved To Spawn")
wait(5)
zombie:MoveTo(workspace.Point.Position)
print("Moved To Point")
wait(5)
zombie:MoveTo(workspace.End.Position)
print("Moved To End")
end

Script works after moving to the spawn point and it goes to the point, but moves back onto the spawn. Help? It's a script in workspace moving the zombies
