Obscurity Portal has two large categories: Strange Things and Normal Things. Everything on the website falls under one of these categories. For instance, xubus is clearly a Normal Thing. Develor is also a Normal Thing. But Infinite Canteen is definitely a Strange Thing. And even Mount Louigi is pretty Strange.

There is a simple rule which defines which is which. Those who figure out the rule are eligible for the honorary title of Whatever and an Obscurity Level increment.
