Bitey Brothers

Bitey Brothers are bounty plants in Plants vs. Zombies: Battle for Neighborville. They can be hunted in Sundrop Hills and come in a group of three. Defeating them unlocks The Bite Stuff medal.

Strategies
Bitey Brothers are invincible when they are outside of the circle area, which is indicated by the presence of a rainbow effect. They become vulnerable once they are inside the circle.

The easiest way to defeat them is to use the Super Brainz, as he is suited for such close quarters combat. Using the Fearless upgrade allows him to become semi-invincible by allowing him to continuously regenerate health when near them, and most of the time they can't attack you quick enough to drain your health below 15 HP. Attack them with the fists and don't worry about dying; being near them with the Fearless upgrade almost guarantees that you won't die at all. If one of the Chompers try to leave the circle, use the shield and aim at the escaping Chomper to lure him back in. Don't use the Hyper Jump Thump ability as it is pointless and can cause some of the Chompers to leave the circle. For a finishing blow, use the Super Ultra Ball and aim at them. This will allow you to gain an extra XP if you manage to kill some of them with it. For best results, use it while all of the chompers are on very low health. You can score up to 75 additional XP if you manage to defeat them all in one hit.

Coin, taco, and XP farming
This particular bounty hunt can be exploited to quickly farm coins, tacos, and XP due to how easy it is. Simply use the Super Brainz with Fearless and Leveling Up upgrades, and defeat them multiple times until you get the desired amount of them. Beating a bounty hunt gives you 5,000 coins, 10 tacos, and at least 725 XP (796 XP with Leveling Up), and defeating the Bitey Brothers takes around 25-45 seconds with one player, so it is a very quick way to farm them.

Trivia

 * There is a glitch where one of the Chompers will occasionally leave the area. This can be solved by approaching them, and going back into the circle.
