Sprout

Sprout is a stationary enemy found in The Crater chapter, spawned by Carnibulb and Infested Pair when those enemies take damage. It has only 1 HP and cannot move, but its possessing puff attack hits all adjacent tiles each turn — converting them to grass tiles and inflicting the Possessed status on any unit caught in range. It is immune to Poison and Water, and does not leave a corpse on death.

Sprouts are not independent threats — they exist to buff the enemies that spawned them. Each Sprout on the field grants Carnibulb +1 movement range, and each Sprout grants Infested Pair an additional turn. A fight against Carnibulb that generates many Sprouts can quickly turn into a chase across the entire map as Carnibulb's movement snowballs. Sprouts are immune to each other's puffing attack, preventing friendly-fire.

Sprouts die in one hit from any attack, so eliminating them is trivial in isolation. The challenge is finding the time to kill them while also managing Carnibulb or Infested Pair's escalating threat. Prioritize Sprouts immediately when they spawn to prevent the buff stacking from getting out of control. Stay away from Sprouts if you cannot kill them that turn to avoid the Possessed status application.
