Fish big enemy leafy seadragon
The real-life sea dragon is a harmless sea-horse which camouflages itself as a strand of seaweed. Aquaria's version, however, is a forbidding miniboss which sprays solar fire. The Seadragon will fire a barrage of solar fire ever few seconds whilst charging at Naija.

Several of them are found in the Kelp Forest maps. The most northeast of these is notable for usually dropping a Special Bulb.
