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. If not destroyed quickly, many phantoms will spawn from it.
- 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 the player either exits (and returns into) the area, which causes the phantom to revert to normal behaviour, or destroys the phantom.
- Sometimes, after a Sprouter is destroyed, the game will lag and another Phantom will spawn while the Sprouter is crumbling.
