[dTal]

Questions 1-5 establish immediately that it's a small, carnivorous, unpleasant animal; you go on to establish that it's inedible, forest dwelling, palm-sized, and can climb. Some sort of spider is an obvious guess. There are other possible answers (tree frog, perhaps?) but spiders rank very highly in human psychology. Your main lesson here should be that you are not as original as you think you are!

Tarantula was indeed picked as an 'easy' start as I've played this before with people.

So I guess you're right, though it's not the way a human would do it, we'd home in faster and more precisely, but still.

As you say, it kind of partitioned off the search space pretty efficiently in its own strange manner.
