The third in the increasingly inaccurately named "Hitchhiker's Trilogy." Tells of the battle to save the Universe from the evil robot warriors of the planet Krikkit, who look suspiciously like cricket players. Mentions the Somebody Else's Problem field, the only practical way to make something invisible. Includes a poem by Marvin, the paranoid android:
"Now the world has gone to bed,
Darkness won't engulf my head,
I can see by infrared,
How I hate the night.

Now I lay me down to sleep,
Try to count electric sheep,
Sweet dream wishes you can keep,
How I hate the night."

Another strange and funny book.
