Redoing this setup since my original solution wasn't very stable

God damn this setup is difficult 💀 This setup got me stressing because everything is so precise and I was kinda obligated to play this because hydroxyl (#1 solution maker) made this solution for me

Solution: ch5u-34.8s, PSD/PDD | IA(Ja)-PD/PSD | IPS-BPPDD ( 6 | 13.3 | 15.5 )

Usually, ch5u rhythms have the long ice wave before the short ice wave but this one switches it around. This is often called the 'ice lantern ch5u' rhythm because ice lantern 14 cob (   • Ice Lantern 14 Cob | Survival Endless   ) is famous for using this rhythm.
I couldn't solve this setup for the life of me because of this unusual rhythm but hydroxyl easily solved it because he's a god. This setup is definitely impossible if you have the long ice wave first

There's a lot of subtleties in this solution and there's a lot of fake solutions that seem like they would work but actually don't. There was a full-defensive 17 cob solution made by chalk: https://www.bilibili.com/video/BV1uN4...
However, the PPSSDD operation on the ice wave was proven not to be rigorous and the PSD/PDD operation on the accelerated wave was also proven not to be rigorous because of the slowed gigas on rows 4 and 5. 18 is the lowest number of cobs to fully defend the field manually right now.

Zombonies are extremely extremely precise.
The ice wave PD/PSD to kill the zombonies is kinda precise. It's easy to time the ice early but other than that I didn't really ever fail this.
The PSD/PDD to kill the zombonies is more than precise. It took me an hour and a half of playing before I did this technique for the first time 💀 After a little bit more practice though, I got it mostly down. You have to drag the second ice wave out long enough so the gigas unfreeze right as you shoot the cob and you have to time and place the cobs absolutely perfectly to barely kill the zombonies. Other people make this look easy
