Enjoy the Captain's poetry (right after one of the four lines). The captain will read the second verse of his poetry. Remember to write down the word that you were told about earlier (Switch on case). Once back in the hold, type the word (remember to use " " quotes or it won't work). Get the plotter.

Put dangly bit in tea substitute. There are five scenarios (all rather short, but each important). They come up in random order. You will be in the dark each time you enter a scenario, so remember to use your five senses.

Upon completion of each scenario you will once again be in the dark place where you originally entered the HOG, so remember to listen. You may want to save your game after completing each scenario.

The Bugblatter beast: Dark...(smell). When the beast charges at you, tell him your name. Run East. Get the sharp stone. Cover your head with the TOWEL. Carve your name on the memorial.

Vl'hurg & G'Gugvunt Leaders: Dark...(listen). This scenario only comes up when you have had the story about the Vl'hurgs and G'Gugvunts, which in turn only appears some time after you have given an unknown command. So, put one in deliberately, if necessary. Get awl. You might listen to the conversation and wait... When you are in the maze: walk around until you find a black particle. Get PARTICLE.

You should have the following: 4 fluffs, ultra-plasmic awl, paint chipper, Nutrimat computer interface card, and tool box. When finished with all the scenarios, pick up the interface card and go to the Nutrimat. Open panel. Remove the circuit board. Put in the interface card. Touch pad. Go to the bridge. Plug the large plug into the large receptacle. Missiles! Push the switch on spare drive. Go to NUTRIMAT. Get tea! Go to the bridge. Drop the tea. Remove dangly bit from the tea substitute. Put dangly bit in the real tea. Drop all (you may keep your GOWN and Babel fish). Get thing (if not in your pocket). Push the switch on the drive.
Sperm Whale. Dark...(keep on looking until your feeling has returned). Get pot.

Put pot in the thing. Wait. ....Dark....

Get 4 fluffs. (Zaphod's and his tool box are near the hatch, Trillian's is in her handbag, Ford's is on the SATCHEL, and yours is the GOWN's pocket fluff.) Go to the bridge. Take the flower pot (you may have to get it from the thing). Plant all four fluffs in the pot. Drop the pot. Wait. Get the pot after the sprout appears. Go to Sauna. Eat the fruit from plant. Pay attention to the vision! The vision tells you what tool Marvin will need to open the hatch. If the tool is not known to you, it will be in the pantry. Get the real tea. Get no tea. Go to the screening door. Open the door. Drink the real tea before entering the pantry. Enter the pantry. Tell Marvin to fix the hatch. You have twelve turns to meet Marvin at the hatch.

Go to the hatch. Drop all, including your GOWN, but not the tool you will give to Marvin. Go starboard. Give Marvin the tool he asks for. Go out to the hatch and then down the hatch.
