Level 5-6

Level 5-6 is the 46th Plants vs. Zombies level and the sixth Roof level. When this level is finished for the first time, the player unlocks the Umbrella Leaf.

Difficulty

 * The Catapult Zombie will be difficult without using any instant kills or Kernel-pults. Since it is a bad idea to use Doom-shrooms and Ice-shrooms (along with the Coffee Bean), one should use the Squash or Potato Mine to destroy it. It is a bad idea to use the Chomper because the Catapult Zombie will move like a Zomboni when it runs out of basketballs.
 * Since no Bungee Zombies show up stealing the player's plants, three Bungee Zombies will drop zombies during the final wave. Since they will place zombies on his or her lanes, he or she must destroy them as soon as possible.
 * In the Nintendo DS version, the Catapult Zombie will start moving close to your house after it fires fewer basketballs. Unlike in the mobile, PC and console versions, the player must be fast and have good defenses so that the Catapult Zombie will not crush his or her plants.

Strategies

 * Suggested plants
 * Sunflower
 * Flower Pot
 * Cabbage-pult
 * Kernel-pult
 * Wall-nut or Tall-nut
 * Squash
 * Fume-shroom and Coffee Bean (if you have seven and eight seed slots)
 * Potato Mine (if you have nine seed slots)
 * Cherry Bomb (if you have ten seed slots)
 * Do not place Kernel-pults in the back lanes because the Catapult Zombie will launch basketballs to deal damage and the plant will be destroyed. In addition, the Pumpkin is also useless when the Kernel-pult is inside because the Kernel-pult gets damaged before the Pumpkin.
 * When a Catapult Zombie shows up, avoid letting it stay too long. If the Catapult Zombie is not killed, it will start moving and crushing your plants. In the Nintendo DS version, you must be fast because the Catapult Zombie will move after it has fired fewer basketballs. Use a Cherry Bomb or any other instant-kill plants (except the Doom-shroom).
 * Only plant Kernel-pults and Cabbage-pults on the third and fourth lanes.
 * Plant Fume-shrooms and Wall-nuts on the flat top of the roof on the seventh lanes only. Never use Garlic, because these zombies will deal more damage to your Wall-nuts. If you want stronger defenses, plant Tall-nuts instead.
 * When the ambush zombies are dropped, plant a Squash near your Fume-shrooms if one of them has landed on your Fume-shrooms. This will save them from being eaten by the zombies dropped by the Bungee Zombies.
 * If possible, plant Wall-nuts or Tall-nuts in the back column to ensure the catapult zombie will not hit any other plants.
