Volcano is the third, and currently final, location in Plants vs. Zombies 3. There is only one plant to be unlocked, Chili Bean, and two new zombies to be encounter, Rock-N-Rollin' Imp and Gargantuar.
It takes place on top of the volcano and on the lawn, there are lava puddles in the background of the field. A nacho stand and a hot tub with rubber ducks is present between the player's camping trunk.
This area also features a "Volcano Eruption!" surprise attack, wherein several falling rocks will descend from the sky and land on certain tiles, leaving behind a crater which prevents the tiles from being planted on. These craters will disappear after 15 seconds, and plants occupying targeted tiles will be instantly destroyed.
