Pitalin is a plant that seems to grow at the far reaches of the island Nexus lay upon, near the beaches. When it blooms, reveals a bulb in the middle of the large circular plant that will explode to shower its seeds around the area.
The explosive material behind the seeds can be taken out a few weeks before it blooms, when crushed will allow for one to make an explosive powdery substance that when exposed to heat will explode.
