Kumquat

Kumquat is the seventh plant obtained in Dragon Dynamite in Plants vs. Zombies: A New World. It forward to a row of zombies, dealing 13 normal damage shots of damage.

If it kills a zombie, it will stop and become a defensive plant that can absorb 20 bites from the zombies (50% the health of a Wall-nut). Unlike Wall-nut, Kumquat is immune to explosions and fire.
