Zhu Zhu = žūžū

Some company may think that "Zhu Zhu" is the trademarked name for a fake hamster. But I have news for that ^$&*! company: "Zhu Zhu" -- "žūžū" -- is a Latvian phrase for a baby bear, or "little bear" ("lāča bērni" [plural?]) -- or, in any event, for cradling, or hushing, a baby bear. The phrase "žūžū" appears in an old Latvian folk song, a lullaby, a folk song that antedates, by several hundred years, any known trademark law in any Western country. First in time, first .... So there!
