As your status line says, you are in the Vogon Hold.
ASK FORD ABOUT THE EARTH.
The Earth has been destroyed by the Vogon fleet. You and Ford have hitched a ride aboard one of the ships of the Vogon Fleet by using the electronic Sub-Etha signaling device, also known as a Thumb.
Hang the gown on the hook, then press the button again.
You'll have to block the drain.
There's only one thing large enough to completely cover the drain.
Cover the drain with the towel, then push the button again.
You have to block the tiny robot panel.
Standing or lying in front of the panel won't work.
You have to put some object in front of the panel.
If it isn't bulky enough, the cleaning robot dashes around it.
The satchel is bulky. Put it in front of the panel, then push the button again.
At this point, brave men have been known to break down and cry.
Read, very carefully, the paragraph when Ford goes to sleep.
When you placed the satchel in front of the panel, the satchel is now LYING ON ITS SIDE in front of the panel.
You can put an object on top of the satchel.
Put something on the satchel, then push the button again.
The upper-half-of-the-room cleaning robot just manages to catch the second item.
If there were several items on the satchel, they would all fly into the air and confuse the flying robot.
Unfortunately, there's only room for one object on the satchel.
Is there an object that when flung into the air might act as many items?
When the upper-half-of-the-room cleaning robot grabbed the
babel fish the first time it said that the fish was "the only flying junk" that the robot found.
Put the junk mail on the satchel, then press the button one last time.
Don't go on unless you've translated the garbled announcement.
Don't go on until you've figured out what's going on with the
glass case and switch and keyboard.
You are at a Vogon Poetry Appreciation Session. The Vogon Captain is about to read you his favourite poem. The Guide's entry on Vogon Poetry makes clear that this is extremely nasty.
You should now know that you have to listen to the second verse (not line) of the poem in order to get the atomic vector plotter.
This poetry is painfully awful. Have you tried to STOP THE POETRY or COVER MY EARS or DON'T LISTEN TO THE VOGON POETRY.
When he finishes the first verse the Captain says, "You didn't look like you enjoyed my poetry at all!" and then has you thrown into space.
Why not relax and enjoy it?
ENJOY THE POETRY while the Captain reads the first verse. He
will continue on and read the second verse.
Now that you've heard the glass case's recording AND the second verse of the poem, you know what to type on the keyboard to get the atomic vector plotter. (When the guards drag you back into the Vogon Hold, of course.)
For example, if the recording asked you to type the second
word from the second verse, and the word was "lyshus," you should type TYPE "LYSHUS" when you get back to the Vogon Hold. NOTE: Each time you play the game, the lines of the second verse come in different orders. Similarly, the glass case's recording asks for a different number word each time you play.
