Basketballs are a projectile lobbed by Catapult Zombies. A single basketball deals the damage of one bite, so six basketballs can eliminate a plant. The basketball's only weakness is the Umbrella Leaf, since it deflects basketballs away from the plants.
- For more strategies, see Catapult Zombie.
The best way to deal with basketballs, or really, Catapult Zombies, is to place a Spikeweed or Spikerock in the first or second column near the zombies. Any Catapult Zombies that appear will explode instantly. However, since players cannot plant Spikeweed or Spikerock in Flower Pots, this strategy will not work in Roof levels.
If a Catapult Zombie's vehicle is not destroyed by a Spikeweed or Spikerock, players could use an Umbrella Leaf to counter the basketballs and prevent them from harming player's plants in the back.
If players want, they can also place a Wall-nut or Tall-nut in the back row of the column the Catapult Zombie is in. This will stall it (until it runs out of basketballs) and players can withstand a lot of damage from these zombies.
Note that Pumpkins will only take hits after their plant inside is destroyed, unless there are no plants with Pumpkin.
- Even though Garlic takes 21 bites to be eaten, it will still be destroyed by six basketballs like most other plants.
