One day, Jack constructs a machine that can transform objects into other things. Then, the song when Oggy is sad plays as he enters the room, recently have been woken up. He then gets his milk, but when a drop just falls, he finds out it is empty. Jack then shows off his invention to Oggy. So he made a bicycle to demonstrate it's primary ability. He used the cockroaches' bed, a tyre and blue paint to create a bicycle. He requested for milk, so Jack brings a cow and milks it with the machine. But oh no! The cow's head can only be seen! The cockroaches move in to see what's going on. They are made into cheese, milk, cow meat, shoes, and bags. He then transforms them back into a cow, the cow puts Jack in the machine.
Oggy then picks up the skin cans. But Oggy realizes that the cockroaches have the bone can. They roll it over to Bob's house, but uses Jack's skin as a skipping rope a round yo-yo, and a boxing effigy. Oggy then builds Jack's whole bone set, which frightens Bob that his whole body turns very pale, and he faints, Oggy then carries Jack's skin and bone set back to Oggy's home and puts them in the machine, but in addition, the cockroaches put in the cow, then Jack becomes a cow. Oggy puts his remains back, but the roaches put the bicycle, then Jack becomes a bicycle as well. He reverts once more, but Joey bangs Oggy's hand. Oggy's hand is on the keypad, so the keypad is banged on too, resulting in a tooth-paste tube housing Jack. When the roaches open it, Jack bangs the cockroaches, crawls with his hand. Oggy picks the tube up, rolls Jack out the tube, thus Jack is saved.
