How do you complete last stand: roof?

Solution 1:

Last stand roof is beaten by using the right plants.

• Winter Melon : Awesome AoE DPS and AoE slow
• Melon-Pult : Awesome AoE DPS
• Umbrella Leaf : Protects itself and all other plants arround it against Bungee-zombies

The first line should be all Winter Melons, this will make sure that the enemy is always slow. Additional Winter melons are not needed seeing they don't do more damage then regular Melon-Pults

Second line should be Melon, then Umbrella, Melon and then umbrella again and lastly another melon.

Third line should only be Melon-pults

Forth line should be just like the second line.

The massive Aoe Damage in combination with permanent slows will give you the victory while the Umrella's protect against bungees.
