Plants vs. Zombies Wiki

A Crazy Orb is an item in Plants vs. Zombies: Garden Warfare, Plants vs. Zombies: Garden Warfare 2, and Plants vs. Zombies: Battle for Neighborville. There are two types of crazy orbs, plant orbs and zombie orbs. The plant orbs are green, while the zombie orbs are purple. Their purpose is to mark the score in Vanquish Confirmed!. Collecting a crazy orb that is of the same team as you will stop the other team from collecting it. Collecting a crazy orb from the opposite team will add a point to your team.

A player vanquished in midair will have their orb float in midair.

In Plants vs. Zombies: Battle for Neighborville, the Crazy Orbs have their respective side's insignia (a leaf for the plants and a "Z" for the zombies), and will slowly float towards a player if they're close to it.
