Trap tile

The trap tile are an environmental modifier in Plants vs. Zombies 2 and only appear in Lost City. They are triggered once a zombies steps on it or once a plant is planted on it. There are two types of trap tiles: One with an icon of a flame on it and one with a rolling rock on it. The one with the rock summons a giant ball from top to bottom, and flicks away all plants and zombies in a limited area, in a similar manner to the Power Toss. The one with the flame acts like a Jalapeno, but releases green flames instead and can burn every plant and zombie from that lane.

 * It seems everything but the boulders that appear through the boulder trap tiles can activate the trap tiles.
