You need your crack.
On the couch is your CRACK PIPE. Take it. In the lower left corner is some vomit. Just to the right of it is a CRACK ROCK. Take it and you’ll use it, revealing Blowie. Talk to Blowie and learn about his problem with the dog of the neightbour. You should do something about it.
Use the door on the right to go to the hallway. Use the door on the right again to knock and get the attention of Shecanteat. Talk to her but she won’t let you in. Talk to Blowie again and ask him to set the plant of fire. That’ll get Shecanteat out of her apartment.
Walk to the right and look at the dog. Use the dog to put it in the microwave. Blowie can be satisfied.
