- Not enough time to gather enough sunlight to plant powerful weapon. The only cheaper options are either cabbage-pult(cabbage shooter) or kernel-pult(corn shooter).
- Magnet-shroom must be planted early to deal with properly.
The solution I found to be effective is to plan Magnet-shroom early (in the front) in a straight line in the middle so that vaulting zombies can be knocked off its pogo stick early so that cabbage shooter can attack it earlier and more effective.
Appropriate usage of pumpkin and cherry bomb is also useful.
