S1·E30 The Monster's Favor

When a boy and his father pull out a gigantic needle that was stuck in a monster's foot, she repays them by working at their shop while the father's injured. While there, she makes special pinwheels out of her feathers. Unfortunately, these attract the vicious Alien Magma, the very alien that destroyed Leo's home planet, who is determined to kill Rolan after she refuses to marry him. This time, Leo can't let him get away!
