First you go to the farm. You will see a house with broken windows. Jump on it.Then enter the chimney. If you look closely you can see glass bowl. Pick it up, then exit through the chimney.Go back to Main Street and go into the Carrot King Diner. Walk around until you see a lady dressed up as a waitress. Click on her and ask her if she can pour some milk into the glass bowl. Then go back to the farm and go in the chimney again. Walk to the end of the room and there should be a box that says up. Jump on top of it and climb up the light.Go into the bathroom and turn on the shower. A gray cat will jump out of the tub. Chase the cat downstairs and lead her to the bowl full of milk. Once she is done drinking it, she will follow you where ever you go. Exit through the chimney again and go back to Main Street. Go into Charlie's Hardware store and give Charlie her cat. In return she will give you a crowbar. Go to the factory and find the vent system blueprint on the roof. Then go down to a big pipe. Open it with the crowbar.
You will reach the factory floor and vents, so you need the blueprints from the outside window near the roof.
Enter the Carrot Cake Factory with the crowbar you get for returning the cat to Charlie's Carrot Surplus. Pick up the Carrot Transporter. Cross the red-capped trap doors one at a time. Dodge the rat by climbing into the upper area.
