Gem 4 Cob | Fog Endless

! Note: Limit setup - too much sun loss (-7k lol)
I wouldn't say it's a hard setup but I wouldn't classify it as an easy either. It is pretty tricky to control Jacks, Snorleks, Zombonis, Pogos, Catapults and Gargantuars at the same time. Glooms at the pool don't have pumpkins, so snorkels can easily eat a one or two. Jacks are pure RNG and it depends on your luck if the pool glooms and front cobs will explode or not. Because Fumes at row 1 and 6 is not protected by leaf, you need to constantly put it at column 4, which are being eaten by imps.
Spikeweed is essential for this setup, because there are waves which you can't use cobs, doom or instas for a bit of time. Fumes are optional but I like them because they are cheap and useful for pogos.
Threats:
Jacks: they are pure RNG and you need to pray that front pool glooms will not explode nor cobs.
Football Zombies: sometimes they can pass through your lawn at row 1-6 so be sure to have a squash ready.
Giga-Gargantuars: they have loads of hp so without cannon fodders (which are in this case spikeweed, umbrella leaf, blover and fume-shroom) this setup is impossible.
Zombonis: without precise spikeweeds the run is impossible.
Snorkels: they can easily eat your front pool glooms if u don't place lily pads to stall them.
Catapult Zombies: without constant placing of umbrella leafs at column 4 they can easily destroy your fume at row 1-6.

I think its better to use cob/ice/cob/ice/doom

This is freestyling so you should not follow a sequence, it is the preference of others to play as they want
