Big Brainz World is the 10th Secret Realm in Plants vs. Zombies 2 with 25 Levels. Big Brainz was first celebrated on September 30, 2016 and featured zombies from both Player's House and Modern Day being showcased with comically large heads. The event also showcased the new premium plant, Apple Mortar, as the associated plant for the event. In 2021, the Big Brainz Event returned, celebrating some of the plants' recent achievements after attending summer school with Dave. The event started on August 16 and ended on September 25 with featured plants being Snow Pea, Snapdragon and Chomper. In 2023, this event returned in a much smaller format, as it did not have Piñata Parties or a Thymed Event, and was only seen in the shop.
