Ive already demonstrated how 90s point-and-click adventure puzzles relied on combining various objects that seem to have been picked at random out of a raffle, and Monkey Island 2 is another shining beacon of this terrible tradition. Youre tasked with retrieving a piece of map from behind a waterfall that runs on a pump. To switch off the waterfall, you need to use a wrench of some sort. After wandering around all the merchants youve encountered in the game to that point, one of whom you'd think would have a spare one knocking about, it turns out that the wrench you need is in fact a hypnotised monkey. Because monkey wrench - get it? Suffice to say, many gamers didnt get it. Even when youve figured out this US-centric wordplay (we call them spanners here in Blighty), to get your hands on a monkey you need to stop it playing on a piano by sticking a banana on a metronome naturally.
