The Jungle is adjacent to the main lane. It spawns a random Demon every 10 seconds. When a team hires a merc, it despawns the Jungle camp to compensate for the 12 demon cap on the map. After the merc is killed, the jungle creeps start spawning again. I'm also not sure if you are mistaking the moba term Jungle as in an actual Rain Forest type environment.

Yeah I saw this one too while making Armies of Hell. Trust me... there are worlds of differences.
