In this video we find out which horde of Tier 0-0-4 Boomerang Monkeys can survive the furthest in BTD6. Also quick rules: 1. I am not allowed to place down another monkey until I have the monkey currently being upgraded to Tier 4 2. No cash drops or buffs 3. Monkey knowledge is allowed 4. Two 1-3-0 villages are allowed 5. If at the beginning of the game I don't have enough money to afford the tower, I give myself enough money to get the MIB and the tower EXACTLY. 6. I must upgrade bottom top bottom top then whatever path it is (e.g. 0-0-0 to 1-0-0 to 1-1-0 to 2-1-0 to 2-2-0 to 3-2-0 to 4-2-0) 7. I must use abilities once i get them Hope you enjoy. #NinjaKiwi #BTD6
