Plantless | Fog Endless

Ideas by me
Solutions:
W1-W9: C2/Ch4u, I-N | I-PA (| I-N | I-PP) - [25 | 25 (| 25 | 25)]
Repeat the bracket until W9. Cherry and others besides the 2 cobs in the bracket are used for other potential threats. This solution is the same as this solution in 3412 Cobless: • 3412 Rectangular Coble... except this one uses cob, better than using jalapeno.
W10-W19: C6u, PP | (PA) (| I-PP | I-PP | PP | PP) - [9 | 9 (| 18 | 18 | 9 | 9)]
Repeat the 2nd bracket until W19. In the 1st bracket in the sequence, you cannot always use PA on W11. It depends on which area is better place a cherry. If many gigas start approaching the starfruits or tall-nuts at any lane(s) as fast as they could possibly can, it is better to place down a cherry and instead of using PA, make sure to start the ice wave on w11 which is a better option if that happens.
This literally took me hours & hours to beat because I turn on extreme spawn which increase the density of gigas. This is both skill-based & luck-based setup. Plantless challenge is actually possible on all 6 endless maps. Playing this "setup" on RE is probably the funkiest one to attempt of them all but I'm not going play the RE & ME variants, unless I recieve an information, solution, tips or videos of those.
Threats:
#1: Gigas: Obviously the top threat... in most of cob or cobless setups. They can sometimes reach close to your tall-nut, smashing your starfruits if you don't pay close attention to them. In rare cases, you will not have enough cannon fodder to fend of the gigas which only happens in extreme spawn
#2: Gargs: Not a very big problem, but they can still cause problems, but small ones.
#3: Jacks: Can blow up you cob cannons if you don't place correctly. TAS should to be used on the doom wave or with cherry to prevent them from exploding your instants.
#4: Zombonis: Annoying zombies because of ice trails all over the place left by them. If you're lucky enough on W2, you can place down a cherry on a lane with no ice trail next to the recently generated gigas, damaging them. Then if they leave ice trails on every single lane, you automatically have to use a cherry far away from gigas that just spawned in and this can sometimes prevent the next wave from triggering.
#5: Imps: Can block the starfruit shots and eat away your plants.
#6: Dolphins: Can hop onto your cobs if don't focus on placing lily pads. Lily pads can be disappear due to jack explosion and gigas can block the view of the lily pads so TAS is really important.
#7: Ladders: They can possibly spawn as a pack on both top and bottom which can also dodge the cobs as well rushing to your plants, blocking your starfruit shots, eating away your starfruits and sometimes climb over your tall-nuts.
#8: Diggers: High tall-nuts pressure can occur.
I messed up on W11 which I mistakenly missed some of the gigas using cobs. This caused the current wave still in place. Glady I time the doom right after W12 started.
