20 Cob Cannon Build Demonstration Flags 1-24 | Survival Endless

This setup is rather hard to build and I had never built it before so I decided to try and build this as fast as possible. I decided to also use imitator flower pots and lily pads just to ramp up the skill required (and to also make the build have more aesthetic).

I got ladder zombies on flag 7 which is pretty lucky but I could have built the setup the same even if I got ladder zombies on flag 50. There are only 8 tiles in which you have to ladder which makes this setup much easier to ladder than other setups. (other setups usually require 10-12 tiles)

Mistakes-

At 3:06 and 3:13 I should not have placed coffee beans on the glooms. If ladder zombies were to try and ladder them, they would probably die before they place the ladder. I had to replace them later.
At 6:44 I forgot to bring sunflowers which brought my sun count down a lot more than it could have. I had to stall to collect sun for 2 flags more than I would have needed to.
At 9:44 I nearly lost my laddered plants
At 13:04 The dancing zombies spawned backup dancers on the cobs but luckily they did minimal damage
At 18:18 I completely messed up the cob to kill the water zombies

Anxiety Inducing Moments-

At 9:32 The balloon zombies were about 3/4ths off of the screen to the left
At 9:44 I forgot that there were bungee zombies and I nearly lost my laddered plants (I didn't have coffee bean loaded because I used it on the ice to stop the water zombies from spawning). Luckily, I had fast enough reaction time and I killed them with cob cannons.
