Two questions, one each for Zork and Hitch-hiker's Guide

In Zork, a friend of mine has scored all but five points, 
and, as far as he knows, "done it all" except kill/catch
(or anything, for that matter) a certain bat attached to
some ceiling along the way. He wants to know what to do
to catch or kill the bat.

Re Hitch-hiker's: How do you get past the screening door
on the Heart of Gold, and get into the room Marvin is
incessantly going into? It's just no fun wandering the
halls of the Heart of Gold, listening to Beeblebrox
slurp his drinks and talking to either hostile or
paranoid computers.
