Being the first stage in the chapter, this stage is pretty easy to beat. You can pretty much get through the entire stage using only puff-shroom and the new sea shroom. However, using fume shroom makes the stage much easier and less stressful.
This stage brings a new zombie enemy which is the jack in the box. The jack in the box zombie blows itself up along with the plant it touches if it stays alive for too long. However, with only puff shroom in the front line, the jack in the box only does effortless kamakazi missions.
