Pneumatic Tube Interface
From A KoL Wiki

- In the center of the Professor's lab sits an elaborate machine riddled with pneumatic tubes. The purposes of these tubes (and knobs and levers) are mostly inscrutable, but one tube, labeled "Fruit Intake Subsystem" gives you the impression that maybe you're supposed to stick fruit into it.
Insert Fruit! |
- Upon insertion of the fruit:
The <fruit> disappears into the tube and begins bouncing around noisily inside the machine.
Notes
- Any fruit will inserted will be projected at the spider, multiplied in the tube, or sent on a collision course with the buried meteor.
