If there was a conversation between mad scientists behind the creation of this creature, it would be the following:
Mad Scientist 1: You know what's awesome? Mechanical Spiders.
Mad Scientist 2: Oh yes, mechanical spiders are super awesome.
Mad Scientist 1: We should make one, then it can terrorise the townsfolk for us.
Mad Scientist 2: For us? Wouldn't we still have to control it?

Mad Scientist 1: No wait I-
Mad Scientist: See ya!
Mad Scientist: Damn... Well at least it will look cool.
