Corny Corn is an NPC in Plants vs. Zombies: Battle for Neighborville. He resembles a Kernel Corn wearing the "Corny" set and is found at Sundrop Hills in Town Center. He gives the player a quest where they must vanquish a Baron von Bats to get his Cool Hat which will be used to create the Lawnmower.
Baron von Bats is no regular zombie. He's a Baron! With a cool hat! Banish that Baron and brandish his bowler! It's not a bowler hat, but you get the idea.
