Swoop Slam is an ability for Snapdragon in Plants vs. Zombies: Battle for Neighborville. When activated, Snapdragon flies up in the air and strikes down to the ground, dealing damage on zombie impact.
This attack can be used to escape or get closer to enemies. It can also be used to get to high ground. It's an effective attack, and a direct hit can deal serious damage to zombies. An effective strategy is to damage zombies with the attack, then use Flame Blower to finish the zombies off. You could also escape zombies and use Flare Ball to finish off enemies from a distance and heal. If you are about to be vanquished, use Swoop Slam then sprint away.
