Bare Facts: Male ~ Born est.1971 ~ Mother Scimitar ~ Father Unknown ~ Children Unknown ~ ID Very straight fin; thin; sharp point; dark saddle

Nimpkish (A33) was born around 1971, probably to Scimitar. He is uncle to all five of his sister Simoom's children, Echo, Misty, Eclipse, Stormy and Hope. He is also now great-uncle to little A83.
While his brother Pulteney hung out with Scimitar, Nimpkish is known as a really fun uncle. Nimpkish especially spends lots of time hanging out and playing with his nephew Echo, and is sometimes called "Uncle 33". Echo's fin is spouting now, so we know these two guys are going to have lots of fun.
Nimpkish makes it easy to identify the A12s. Before Echo's fin began to spout, Nimpkish was the only one with a tall fin. And his fin is very straight, making it especially noticeable. Even now that Echo's fin is growing, Nimpkish is still the easiest in the family to identify.
He most likely got his name from the Nimpkish River.
