(Crazy Dave and Penny appear)
Crazy Dave: Huh, another different-looking box. There aren't tacos in it anyway.
Penny: No, there aren't. This is Upgrade Saisen Box, can make the plants and zombies nearby upgrade. Please use it carefully.
- 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.
