Sneaking into the bear enclosure at the zoo and penetrating different orifices on each bear in the order: 1. Anus 2. Ear 3. Nose 4. Mouth. There is no 5.

Ok this base has only been accomplished by one person, and he died shortly after. This base is really simple, it just takes years to complete. Ok get a girl and dehumanize her for around 10-20 years (however long it takes). Once she is turned into a animal, cut off her arms and legs, make sure to burn the stumps so as not to cause death by bleeding. Ok so now you have a torso + a head that is not human. now cut out her eyes, destroy her ears, and use a cheese grader on her whole body, finally cut off her nose. Finally shit off her body, spear your feces all over her (her body should be holey/bleeding b/c of the cheese grader) then let the feces harden, and then (this takes a bit of time, you could prepare this before hand) pour a jar of (YOUR) sperm on the dried harden feces, after this has hardened bake her in a oven, if she has died you have failed and you only get credit for 999999999 base. ok now the oven has properly killed her, eat and enjoy
