Bridge (Bugbear Mothership)
The Bridge is the final room of the Bugbear Mothership. It can only be accessed after restoring power to all the elevators, but the final encounter can not be fought until you've reached level 13 and compelted the Council quests.
With a Jeff Goldblum larva:
You hold the Jeff Goldblum larva in the palm of your hand. It looks at you, smirking, muttering in its tiny, slow voice: "Now you're the purveyor of... You're the generator of... You're the author of... Great... Stuff..."
Then it vomits a massive spray of acid onto the lock next to the bridge door, completely dissolving it. The lights above the door turns from red to green, which is the universal symbol for "unlocked."
The larva crawls away, muttering something about life finding a way.
