Phantom Sprouters are dangerous plants in the Adventures that will spawn Phantoms and block their path as soon as a player is in range. They must be destroyed with a Boomseed before they spawn too many phantoms.
- Make sure the Boomseed hits the very center, or else it will not work. Boomseeds striking the small pipes will not do anything except to destroy phantoms.
- Phantoms sprouted by the Sprouter, as long as they are out of range of the Boomseed, will remain alive and will stalk and attack the player until they're destroyed.
- Sometimes, after a Sprouter is destroyed, the game will lag and another Phantom will spawn while the Sprouter is crumbling.
