Everyone is enjoying Loopy's sandwich. When there is only one piece left, Eddy brings out his cloning machine to make more sandwiches. He puts a sandwich in the machine and...tah tah~ Sandwich is cloned. Eddy heads to tell the news to Rody. Crong comes by at Eddy's house and accidentally goes in the cloning machine. Now there are two Crongs! The two of them head home and when Pororo asks who the real Crong is, they start to fight. Eddy says that his machine can reverse the cloning and puts both of the Crongs in the machine again. But when the door opens... there are 4 Crongs coming out!
