Backup Dancer

The Backup Dancers are summoned by Dancing Zombies and appear in sets of four around them, dancing around him showered by disco lights. He is the tenth Zombie you will encounter in Adventure Mode. This zombie is also encountered when you encounter the Dancing Zombie. Unless you kill the Dancing zombie first.

Note: The old Backup Dancers would dance Michael Jackson's Thriller around him.

These zombies appear in sets of four whenever Dancing Zombie rocks out.

Toughness: low

Backup Dancer spent six years perfecting his art at the Chewliard Performing Arts School in Zombie New York City.

Strategy
Kill or hypnotize the controlling Dancing Zombie, or he will continue to summon Backup Dancers when any of them die. Alternatively, plant a Wall-nut in front of the hindmost one or freeze one, because when one stops or is slowed the rest are forced to. Backup Dancers are affected by Hypno-shrooms.

The Dancing Zombie will re-summon missing Backup Dancers about every square if any are missing. Backup Dancers will continue after the Dancing Zombie is killed. They form up a square around the Dancing Zombie. Therefore, a Cherry Bomb planted right next to the Dancing Zombie will instantly kill him and at least two Backup Dancers.

Early on, Fume-shrooms are a good idea against them. If you beat Adventure Mode, you can also use the Melon-pult or Winter Melon.

Wall-nut Bowling 2 Mini-game
If you place a Wall-nut the moment a Dancing Zombie walks onto the lawn, it should roll past the lead Backup Dancer just as it is emerging from the lawn. If you fail to do this in time, it is necessary to plant two Wall-nuts in quick succession or the Dancing Zombie will have time to summon more Backup Dancers. If there are four Backup Dancers that surround the Dancer Zombie, and you roll a Wall-nut to the front Backup Dancer, it will always ricochets to the next, and then bounce to the back Backup Dancer. This will leave the Dancing Zombie unprotected, leaving an open space (And time) to kill the Dancing Zombie.

Another strategy is to bounce a Wall-nut off of the front Backup Dancer, after which it will usually ricochet off one of the side Backup Dancers (and possibly hit the back one too), and immediately follow the first Wall-nut with another to take out the Dancing Zombie while it is unprotected.

Otherwise, if it is too urgent, you can use a Giant Wall-nut to kill both them and the Dancing Zombie, even though not all of the Backup Dancers will be killed.

I, Zombie Puzzle Mode
Placing the Dancing Zombie in the middle lane can help get Brains 2, 3, and 4, in addition to dealing with threats with faster Zombies (if needed) that are vital to part of your success. In Zomboogie, they are also the most helpful zombie. Only use them in the middle rows (2, 3, and 4) where they are most effective, and try not to get the Dancing Zombies killed. The best way is to start with row 2 or 4, and then do it on the other.
