Re: Big Wave Beach Day 29, lily pad (Lv5) cannot be planted before battle
Yes, Zero sun plants cannot be planted before the game starts. This restriction also applies to potato mine and a few other plants.
I did ask a long time ago is that if player can be given an option to down grade their plant level as at that time I have a level 5 profile and accidentally upgraded a few plant in error and so ended up a level 8 profile instead.
I look at it this way now that we have higher level plants so with better experience and be ready to take up a more challenging game. Day 29 of Big Wave Beach is indeed one of the those challenging game. Just trust yourself, it can be done with only the pre-planted 6 pads.
