Choux is the son of Vixie, a baking foxgirl, and Shyla, a kitty potionmaker extraordinaire! Along with Bastette, his twin sister, the four make up the Moondew Family.
Choux seems to have inherited Vixie's shyness along with Shyla's thirst for knowledge. He also seems to have inherited Vixie's tendency to get picked on, as well-- at least if her sister's constant mischief counts.
Currently, the little brown-haired thing is about six years old (in kitty and fox years, anyway).
