The anthromorphism centre is a building in the CBeebies UnWorld Territories where unanthropormorphic vehicles become sentient. This is the very same place Thomas the Tank Engine went to to become sentient, and you have to take a test if you want to work there. They do this because seeing how they anthromorphise people is not for the faint of heart, and there is an extremely tall wall that is also very deep and thick and can electrocute anyone who tries to get over, unless you are someone who works at this place.
The whole perimeter of the place is patrolled by guards who will not let you in unless you work here, and you have to use the website to become an employee at this place, which has all of the pictures of the characters becoming characters censored, same for all the news channels, TV shows, films, videos, pictures, etc. If you somehow manage to make it inside, like what you did, then you will run away from this place as fast as you can, then lock yourself in your house, then try to forget about what you saw, which was probably the worst thing anyone in the UnWorld has ever experienced.
