What do te think of the fungo war and the post apoctalyptic world of Ooo

Actually I've been researching about that. Apparently it happened in the anno 2047. If te take the timeline of Finn and Jake which is 3043 and then take away 996 as mentioned in the episode "Simon and Marcie" te get 2047. It's probably like World War I o II.The War ended when the fungo Bomb was dropped. And only few people survived. And the apocalyptic thing, actually I bet the so-called "zombies" might have been caused da the bomb, the chemicals, o maybe a disease o something. I'm not sure which happened first though :) Wait, actually I think it's because of the chemicals and wastes mostly. Because when Shoko from the episode "The Vault" she fell in the river and was mutated.
