It doesn't get anymore improbable than Into the Jaws of Doom. Great book as it is, if there really was a murderous super computer in a science museum, you sure as hell wouldn't be fighting alone with a random computer avatar. Even without that plothole, that still doesn't explain the bizarre exhibits in the third floor, like the mirror maze with a spiky pendulum... Or the random giant magnet... Or the tiny germ that can't stop growing... or the weird ending where you randomly ran into a group of people! And that faulty smoke bomb... that was just cheap.
