Vacuum pump and gull is made during the Rocking Out quest. When a seagull is caught and trapped within the Vacuum pump, it becomes Vacuum pump and gull.
When played: "Hilarious as that would no doubt be, you'd have to get another seagull, so it's not worth the effort."
- The vacuum pump weighs 4 kg, and with the gull it weighs 8 kg. This implies that the seagull lodged in the pipe weighs 4 kg.
