Disco Disaster

Disco Disaster is a world in Plants vs. Zombies 2: It's About Time. New gimmicks include Disco balls, music, and more. Disco balls will temporarily make zombies faster, and music can damage both plants and zombies.

The surprise attack is called a "DANCE PARTY!" which will make tons of Basic Dancer Zombies come out. Music will then play in this ambush.

Description
Dance and party all night in the 1980's! Oh, and watch out for some sweet moves.

All Night
All Night is a Brain Buster for Disco Disaster which is a conveyor belt and only Backup Dancers come, except when the Disco Zombie comes at the last wave. Music will always play through this level, and disco balls are now more common.

Save Our Seeds
In this one, you'll have to save 3 Twin Sunflowers.

Last Stand
Like every normal Last Stand. Sun plants cannot be used.

Music
In Disco Disaster, Boogie Your Brains Right Over Here from Garden Warfare is the main theme, with the Ultimate Battle and Demonstration mini-game music being the ones from Far Future.
