It likes to find new locations. Like, we've been to a twisted Wonderland, a messed up world where there were giant man-eating bugs, a dino theme park, and so on and so forth. And if it's not taking us to new places, it's making us younger, messing with our food, locking us up or locking us out, or making us have sex for 24 hours straight, or it's sending killer animals our way. That list goes on and on too.
