Dragong

"The Dragong's lithe body belies incredible strength and resilience, which it uses to absorb the vibration of its tail- and feet-plates. In addition to the cymballike clashing they create, these plates allow the Dragong to skim the water's surface, and unsurprisingly, to prepare delicious dishes for its ethereal cohorts." Elements: Mech, Poison
