Unfortunately, the other universe (and its hill) are made of antimatter, so when Derpy opened the portal, the two hills annihilate each other (along with Rambo, Dayrl Dixon, Fredy Kreuger, the zombies, and the family). Most of the energy from the explosion is channeled into the portal, collapsing it. I had been away looking for pie, before I remembered that intelligent life still hasn't evolved yet on the alternate world, so there is no pie. When I get back, I see the hill is gone and only a crater remains. So I go find another hill instead. My hill.
