Use the tractor and find the key among the plants in the field
You will be sent to help the sheriff in the Northern part of the city. He will send you to a farm (you can use a horse to get there). On the farm, there are several things to do:
- Fix the tractor,
- Fill the tractor up (you can find fuel by following the scanner's readings),
- Use the tractor to find a key in one of four corn fields,
- Use the key to open the garage, where you find a farmer's disguise.
Using farmer's disguise, you can water plants in pots. They immediately grow up and form a ladder, thanks to which you can reach places on heights. Climb onto the rooftop of the barn.
You will notice a new chicken icon there. Stand in the icon to see a location specified, where you can get using the chicken. Toy activate it by jumping and pressing the jump key again, while in mid-air. You drop using it, like with a parachute, and you can point the direction in which you want to go. Make it over to the last building, where you will use the sound scanner.
You will locate the first pig on the rooftop, behind the smaller barn on your right. After you have located the animal, fly over there. To lead the pig to the sty, you simply have to jump onto it and ride it (just like any vehicle) to the destination. You have to gather 3 pigs this way.
You will not have any problems with the second one, but you may with the third one. To wake it up, you will have to give it an apple and a banana. You can find the apple to the right of the pig, in a small tower, behind the locked grate. There, you have to water the tree and, after it grows, pick up the apple from the ground.
After that, walk over from the tall tower to the left of the pig. Make it over to the top of the tower and activate the chicken there to get over the train tunnel mouth. There, you will find banana seeds, from which you will harvest the banana. Return onto the castle using the teleporting device. Finally, place the pig in the cannon in the center of the castle and fire it into the far,. This is the last thing that you have to do in this chapter.
