Synergy! was a secret achievement in Plants vs. Zombies Adventures. It was earned by using five different types of plants in a level. Synergy! could be easily earned once the fifth seed slot or a VIP plant was unlocked. It was impossible if the player has not unlocked more than four seed slots, excluding the VIP slot.
