(Crazy Dave and Penny appear)
Crazy Dave: I wish these prehistoric zombies would just go back to their caves.
Penny: User Dave, perhaps it's time to try a new tactic.
Penny: Data suggests Stunion would make for a... potent... ally here.
Crazy Dave: Great idea, Penny! That guy's breath is stunning!
Crazy Dave: Not even exaggerating. He stuns zombies... with his bad breath.
Crazy Dave: Gross. But also, pretty nifty!
(Crazy Dave and Penny leave)
- The small number next to the zombie icon means that zombie will always appear in that lane, with 1 being the topmost lane and 5 being the bottommost one.

- Bloomerang will be your main offensive plant. This is unfortunate because it is relatively weak. However, all is not lost, as you still have the ability to hit multiple zombies.
- Stunion will be a great help here. Make sure to use it when things get hairy.
- Use Citrons to your advantage once available. Leave the first column for them.
