Sprout

Sprout is an immobile Crater enemy that dies in a single hit but creates serious problems while it lives. Each turn it puffs, converting adjacent tiles into grass and inflicting Possessed on any unit nearby. It is summoned by the Carnibulb boss at the end of each of its turns, and each living Sprout on the field increases Carnibulb's movement range by 1 — making rapid clearance essential. Other Sprouts are immune to its puff attack, and it leaves no corpse on defeat.
