To begin, speak to Veronica, who is located in the southern gates of Draynor Manor. Veronica tells you that her husband, Erenst and her were a bit lost, so Ernest went into the manor up ahead. An hour later, Ernest has not returned. She asks you to venture into the manor to locate her husband.

Enter the manor to the north, avoiding damage you might take from the aggressive trees here here. Note that once you enter, you cannot leave the same way you entered through the main doors - but no worries, there is an alternate way to return safely outside.

From the very first room of the manor, you will notice an old set of staircases. Ignore the staircase, and head north, into a hallway that leads east and west. Take the western hallway and enter the first room you come across. Inside this dark room, you will notice a small range, as well as another door that leads into a smaller room. Inside this small room, is a little green bottle of poison. Get the bottle, and return to the main entrance of the manor where you first found the old staircase.

Ascend the staircase to the second floor of the manor. From the second floor, head east into a small hallway, then west into a partially small room with red wallpaper. From here, take an eastern turn to come across a small room which is home to a ghost. Enter the room, and ignore the ghost at all costs, grab the small blue package of fish food from the floor, and sprint back to the entrance of the second floor to avoid any damage from the ghost. With the bottle of poison you acquired earlier on the first floor, combine the fish food and poison to create poisoned fish food.

Upon returning to the old staircase on the second floor, take a west turn, and up a flight of spiral staircase. On the third floor of the Draynor Manor, you will find a roaming chicken, and Professor Oddenstein.

Speak with the Professor, and tell him that you're looking for a guy called Ernest. You will eventually discover that Ernest is actually the chicken that's roaming around in the room. Demand to the Professor that you change him back immediately. Unfortunately, you will soon find out that the machine needed to convert Ernest is broken down. He asks you to find the pressure gauge, a rubber tube, and an oil can to successfully get to machine to work again.

From the first floor of the manor, head to the westernmost room, and click on the bookcase to reveal a hidden door, opening into a dark room with a ladder leading downstairs. Head down the ladder to the basement of Draynor Manor. Examining the basement, you will notice several locked rooms, red levers, and a room to the west, home to the oil can we so desperately need. However, obtaining the oil can won't be as easy as you think. If you right click on each level located around the room, you will notice that each one is marked with a letter. Refer to this map of the basement with the instructions below to solve this lever puzzle.

1. Flip levers A and B down, and enter the northeastern gate.
   
2. Flip lever D down, and enter the southwestern gate, then enter the southern gate.
   
3. Flip levers A and B back up. Enter the northwestern gate, then enter the western gate. Now enter the northern gate.
   
4. Flip levers E and F down, then enter the eastern door, and the eastern door once again.
   
5. Flip lever C down, and enter the northwestern gate, then enter the western gate.
   
6. Flip lever E back up, and go through the eastern gate, then enter the southern gate, followed by another southern gate.
   
7. Enter through the western gate, and claim the oil can.
   

Leave the basement by climbing up the ladder, and exiting the dark room by pulling the red lever beside the bookcase door.
