Giant Wall-nut

The Giant Wall-nut is a free plant only found in Wall-nut Bowling 2 and the cancelled Mini-game Big Time. It looks just like a Wall-nut, but bigger, and acts like a Jalapeno and Squash combined, as it squashes all the zombies in the lane that it is planted in. Even if you squash 5 zombies, you will still not be awarded with the "Roll Some Heads" achievement because you have to use an ordinary Wall-nut to get it.

Strategy
Save them for huge waves of zombies, they will defeat all zombies in their path, making them a great opponent for Buckethead Zombies, Screen Door Zombies, Zombie Yetis and Gargantuars (which will only appear in the two-player Co-op mode in the Xbox Live Arcade version). Also, they are great for destroying Dancing Zombies, as they can smash their Backup Dancers along with them, instead of trying to kill the Backup Dancers separately. However, the best strategy is saving as many Giant Wall-nuts as possible and throw them all out, one in every lane will easily dominate the waves of zombies.

Trivia

 * In Wall-nut Bowling 2, the Giant Wall-nut is similar to a Tall-nut because a Pole Vaulting Zombie cannot jump over it.
 * In games outside of Wall-nut Bowling 2, however, Pole Vaulting Zombies can still jump over a Giant Wall-nut.
 * Giant Wall-nut also appears in Big Time.
