Possible Uses

 * If you put tall-nuts in front of a bladderward, the zombie eating the tall-nut will be killed by the bladderward. I chose tall-nuts because they have the highest defense.
 * If there is a huge wave of zombies, bladderward can save some plants from being eaten by the wave of zombies.

Other Stuff

 * The name comes from bladderwort and ward, ward means to guard or protect something or someone.
