Were you looking for the Mammet which appears during the Goldsmith quests called Gigi, the Item called Gigi (Item), or the Minion called Gigi (Minion)?
Hildibrand found this clockwork automaton deep within the snows of the Coerthas western highlands. Amazingly, Gigi exhibits the traits of personality, but for some reason seems to have lost all his memories, rendering much regarding his origins a mystery. The mammet also appears to possess some faculty with the arcane, proof of his ability put on display when he restored a shattered vase in the blink of an eye.
Notes: This Mammet, and the one that appears during the Goldsmith quests, share the same name but are not related.
