Bomb Cropsies are like the normal cropsies but have a countdown number on them. Once this number has reached zero they will explode and destroy part of your harvest. Bomb Cropsies do not score. Neither will they be added any bonuses. At the end of a level they may be harmless if their count is higher than the number of remaining moves. Hero Mode will convert the bomb cropsies into normal ones.
Bombs are first seen in Level 236.
