When the player goes through the level in No Petals mode and breaks a Crystal Block that was a Health Flower in normal mode, incorrect particles may spawn during its destruction, and may include small rock particles and large leaf particles (ones that spawn after destruction of foliage blocks).
The type and amount of incorrect particles seems to depend on the amount of tiles of that type that were destroyed during the level before popping a Health Flower-turned-into-Crystal Block.
Restarting from Checkpoint seems to reset the amount of incorrect particles to zero.
For example, restarting near a Health Flower before the final Boss run and smashing it immediately will produce no incorrect particles.
Restarting in that same place, going back to destroy a few foliage blocks and then smashing the Crystal will spawn 1-2 "large leaf" particles.
Restarting in that same place, going back to destroy lots of foliage blocks and then smashing the Crystal will spawn a significant amount of "large leaf" particles.
