Once upon a time , there was a huge mountain that covered the Earth. Then some C4 and Gun came along. Electro tried to set Gun off but It didn't work. Then a great ball of fire came and smashed into C4 , who blew the top off the mountain. But it still didn't work. Then gas came everywhere and Electro set it on fire , and then Lava poured over the mountain , but nothing happened. Then god took his hand(which was made of Acid) and squashed the mountain. And that kids , is how all the mountains in the world came to be.
