|“||Although there are said to be some weird things under the sands of the Amber Slavelands, things that have been cut off from the rest of the world for so long that they've developed in their own peculiar way, like Brainless Leg-Removers, Shooters, and Slitherfangs.||”|
|— How to Seize a Dragon's Jewel|
There is no further information for this dragon, and not much can be gleaned from its name, other than perhaps it "shoots" something. Since Brainless Leg-Removers are classed as Sea Dragons, perhaps Shooters can be, too.
Shooters are mentioned only once in the Book series, as a dragon that occurs in the Amber Slavelands.
