Arnold was Ginny Weasley's purple Pygmy Puff, or miniature Puffskein, purchased from Ginny's brothers Fred and George Weasley at their shop, Weasleys' Wizard Wheezes, in August of 1996. Arnold enjoyed playing in front of the fireplace in the Gryffindor common room at Hogwarts, and sitting on Ginny's shoulder, where it often attracted the attentions of Crookshanks, Hermione Granger's part-Kneazle cat. It is likely Arnold was taken with the Weasleys when the family went into hiding in the spring of 1998.
