Space Quest 6

Easter egg:
-----------
There's an imperial shuttle from Star Wars in the DeepShip's shuttle
bay (along with the message: 
"Remember your parking space, Luke!").

The alien from Scott Ripley's "Alien" pops up after Wriggley (pun 
intended) helps you restarting the stolen ship's engines.

Laurel and Hardy are disguised as guard nanites near the entrance to
Stellar's brain.

A graffitti in the DeepShip 86's brig reads "Sarek lies!". 
Sarek is a character from Star Trek.


Unlimited Points:
-----------------
When inside Stellar's stomach, retrieve the secretion from the Isles
of Langerhans, return to the stomach to pour the contents over the 
pill, then collect more. Each time you gain 3 points, and you can 
continue doing this for ever.
